- the perturbation element 108 is a steel screw or nail or rod or pin constituting a ferrous body made of a ferrous material.

- the rests 107 may be formed of plastic and/or metal, or any other material, or, in some embodiments may be divots or indentations in the bottom plate 102.
- the permanent magnets 106 of the arrangement 104 are fixedly arranged on (or attached to) the rotating body 102 such that an asymmetric magnetic field is generated, with a resultant major magnetic field 114 (or major field 114) and minor magnetic field 115 (or minor field 115), about one or more perturbation points 116A, 116B, 116C, 116D (collectively“116”).
- Each perturbation point 116 has a cluster of four magnets 106 circumferentially surrounding the perturbation point 116, with each magnet 106 having an equal radial distance from the perturbation point 116 or substantially equal distance. Some clusters share one or more common magnets 106.
- each cluster of magnets 106 there are three magnets 106 with an upper surface having the same north (N) polarity facing away from the rotating body 102 generating a major field and one magnet 106 with an upper surface having a south (S) polarity facing away from the rotating body 102 generating a minor field 115.

- the magnets form a co-planar matrix pattern to form an H-pattern magnetic flux line of the major field 114. While this embodiment shows there being a greater number of magnets 106 for generating the major field 114 than the number of magnets 106 for generating the minor field 115, it is within the scope of the present disclosure for there to be a great number of magnets 106 for generating the minor field 115.
- the magnets 106 generating the major 114 field may be less in number but“stronger” than the greater number of “weaker” magnets 106 generating the minor field.
- the magnets 106 for either field 114, 115 do not need to be of the same shape, size or strength, and there may be different magnet types/shapes for one or both fields 114, 115.
- the flywheel rotating body 102 is about 15” diameter x 1.25” thick and is about eighty (80) pounds and is a automotive/truck flywheel.
- the alternator/generator 112 is a fourty-eight (48) volt permanent magnet generator, model
- FREEDOM PMG made byMissouri Wind and Solar that reachces battery voltage at 266 rpm.
- alternators/generators are within the scope of the present disclosure.
- the housing enclosing the permanent magnets 106 may be an enclosed high ferrous steel cylinder having an 8” outer diameter x 7” inner diameter x 2” height capped with an 8” diameter x 1/4" thick ferrous steel disc on the bottom and a 8” diameter x 1/4" thick aluminum cap on the top.
- the cap, bottom, and sides may be made of a ferrous material or non-ferrous material.
- the permanent magnets 106 may be, for example and without limitation, 1-1.25” diameter x 0.5" thick (or high)
- NdFe/cylindrical rare earth magnets magnetized axially.
- the permanent magnets 106 can be purchased“off-the-shelf’ from K&J Magnetics, Part Number DX48.
- the perturbation element 108 is arranged at a perturbation point 116 (or near a perturbation point 116) in an initial position such that a longitudinal extension of the perturbation element 108 is parallel to the perturbation axis 118 (or perpendicular to a surface of the rotating body 102 at the perturbation point 116) and then actuated to deviate from the perturbation axis 118 through a provided input force (or applied force) in a direction 120A,
- the perturbation element 108 may be inserted at a substantially central part of the perturbation point 116, but systems and methods may work when the perturbation element 108 is radially offset from the central part of the perturbation point 116.
- the central point of the minor field 115 is in alignment with the central point of the magnet 106 having a south polarity (S) facing away from the rotating body 102 (or bottom plate).
- the actuation of the perturbation element 108 to deviate away from the perturbation axis 118 in this manner causes a distortion (or perturbation) of the asymmetric field 114, 115 and generates a resulting tangential magnetic force on the permanent magnet arrangement 104 and/or the rotating body 102 about the rotation axis 110, thereby causing the rotating body 102 to rotate about the rotation axis 110 in either a counter-clockwise direction 122 or clockwise direction 124 assuming the tangential magnetic force is greater than the friction and/or load resisting the tangential magnetic force.
- the permanent magnet arrangement 104 allows for counter-clockwise direction 122 rotation and clockwise direction 124 rotation, which may be considered a forward and reverse option of bi-directionality.
- rotation of the rotating body 102 may be caused by actuation of the perturbation element 108 to deviate from the perturbation axis 118 in any direction. For example, a wobble of a few degrees of the perturbation element 108 from the perturbation axis 118 will also cause rotation of the rotating body 102.
- the input force required to actuate the perturbation element 108 to deviate from the perturbation axis 118 is less than the resulting tangential magnetic force acting on the rotating body 102. This is possible due to the potential energy contained in the permanent magnet arrangement 104 that generates a tangential magnetic force to drive the rotating body 102 to rotate about the rotation axis 110 that is larger than the input force (or applied force) provided.
- the present disclosure provides a permanent magnetic-driven force amplifier.

- the perturbation element 108 may also be a permanent magnet, such as, for example, a conical magnet, a cylindrical magnet, or the like.
- a perturbation element 108 in the form of a magnet may provide for greater amplification of the input force (or applied force) by providing greater distortion or perturbation of the asymmetric magnetic field than a similar mass, size and/or shape ferrous body perturbation element 108.
- the mass, size and shape of the perturbation element 108 may be adjusted as desired to achieve the desired magnetic field perturbation properties of the perturbation element 108, for example, strength or tuning the amount of tangential magnetic force per degree or distance of actuation 119 of the perturbation element 108.
- greater amplification of the input force may be achieved by arranging a bias magnet to the ferrous control rod with the same polarity as the polarity of the side of the magnets 106 facing away from the rotating body 102 that generate the minor field 115 is arranged on the upper, or distal end, of the perturbation element 108.

- the actuation of the perturbation element perturbs the asymmetric magnetic flux field line 420A and generates a resulting tangential magnetic force on the wall magnets 406, bias magnets 407 and/or the rotating body 402 about the rotation axis 410, thereby causing the rotating body 402 to rotate about the rotation axis 410 in a counter-clockwise direction 422 assuming the tangential magnetic force is greater than the friction and/or load resisting the tangential magnetic force.
- the upper surface of the bias magnets 407 may have the same polarity (N-N; or S-S).
- N-N the same polarity
- S-S the magnetic flux field line
- the magnetic flux field line would have the shape of the magnetic flux field line 420B on the right side of the axis 410. This configuration allows for bi-directional rotation of the body 402.
- a perturbation element 408 actuated at the perturbation point 416 at the bias magnet 407A, in the direction 430 A, would cause counter-clockwise 422 rotation of the rotating body 402, while actuation of the perturbation element 408 (or actuation of a second perturbation element 408) at the perturbation point 416 at the bias magnet 407B, in the direction 432B, would cause clockwise 424 rotation of the rotating body 402.
- One of the two bias magnets 407 is optional and may be removed. For example, if the bias magnet 407B is removed, then the magnetic flux field line 420A would only deviate from the equator substantially at the single bias magnet 407 A. In this embodiment, there would only be one perturbation point 416 at the single bias magnet 407A.
- a permanent magnet asymmetric field system 100H is shown in accordance with embodiments of the present disclosure.
- the system 100H includes a rotating body 502, a permanent magnet arrangement 504 having a plurality of magnets 506 similar to the arrangements 300A, 300B in Figs. 8 and 9 and a perturbation element 508.
- the system 100H further includes a perturbation element guide (or support) 510 defining a perturbation element opening 512.
- the perturbation element opening 512 is configured to receive the perturbation element 508 and is located around a perturbation axis 514 that would cause motion of the rotating body 502 if the perturbation element 508 is actuated to deviate from the perturbation axis 518 or towards a magnetic flux field line as discussed herein in connection with other embodiments.
- the perturbation element guide 510 serves to limit the range of deviation of the perturbation element 508 from the perturbation axis 514 (or distance 119 (Fig. 1) from a magnetic flux field line).
- the guide 510 may advantageously prevent the perturbation element 508 from by an actuating device such as an electric motor and/or gravity weight such as in FIGS. 5-7, i.e., being actuated by a distance greater than required or desired.
- the guide 510 may also advantageously constitute a stop to prevent the perturbation element 508 from being moved by the magnets 506 when the perturbation element 508 is not being actuated or held by an actuating device.
- the guide 510 may be a cover or cap with a hole 512 and may be used with any embodiment herein to limit the range of motion of the perturbation element 508.
- the perturbation element opening 512 may be any size or shape as is desired or as the application requires.
- the perturbation element opening 512 may be a circular hole, a straight slot, a curved slot or a zig-zag slot.
- other shapes are within the scope of the present application.
- FIG. 13 while the embodiments discussed above have been in connection with systems having a rotating body that rotates about a rotation axis permanent magnet asymmetric field systems that generate non-rotation motion (e.g. translational or linear motion) are within the scope of the present disclosure.
- a permanent magnet asymmetric field system 1001 is shown in accordance with embodiments of the present disclosure.
- the system 1001 includes a linear motion body 602 having a plurality of bearings (or wheels) 603, a permanent magnet arrangement 604 having a plurality of magnets 606, and a perturbation element 608.
- the permanent magnet arrangement 604 generates a major field and minor field as discussed above in connection with other embodiments.
- the perturbation element 608 is deviated or moved towards the minor field in a direction 610, the resulting magnetic force on the magnets 606 and/or the linear motion body 602 causes the linear motion body 602 to move in the direction 612.
- the bearings 603 serve to reduce the friction or resistance the linear motion body 602 may encounter in being forced to move in the direction 612.
- the linear motion body 602 is shown as being arranged in an optional linear track 614 which may have guard rails.
- the linear track 614 confines the linear motion body 602 to prevent the linear motion body 602 from moving in any non-linear directions from the track 614.
- the bi-directionality discussed above in connection with rotating embodiments is also applicable to linear motion embodiments.
- the magnets are arranged to work facilitating rotation in structures such as wind turbines, which may significantly reduce the input energy required to initiate rotation of the wind turbine.
- the perturbation of the asymmetric field causes a release of potential energy from the permanent magnets into kinetic energy in the form of angular or linear (translational) velocity or acceleration.
- angular or linear (translational) velocity or acceleration we have found that small input forces acting on the perturbation element positioned at or near parallel to the rotational axis (or perpendicular to the floor of the arrangement) causes an amplified output force due to such energy release (or conversion to kinetic energy).
- the permanent magnet arrangement While specific permanent magnet arrangements have been shown and described as generating the asymmetric magnetic field(s) about the perturbation point(s), it is within the scope of the present disclosure for the permanent magnet arrangement to be virtually any other shape or configuration, or number of magnets, as long as the arrangement is configured to generate an asymmetric magnetic field about the perturbation point(s). For instance, a permanent magnet arrangement that would otherwise generate a symmetric magnetic field about the perturbation point(s) but for the presence of magnetic field shielding, interfering or diverting structure(s) are within the scope of the present disclosure, i.e. the magnetic field shielding, interfering or diverting structure(s) ultimately causes the permanent magnet arrangement to generate an asymmetric field about the perturbation point(s).
- the magnetic field lines shown and described herein are an approximation of the location of the magnetic fields.
- the actual shape and location of the magnetic fields or field lines may be different than as shown and/or may vary based on physical characteristics and materials of the system.
- a magnet side (or surface) having north pole N polarity may instead have south pole S polarity and a magnet side (or surface) having south pole S polarity may instead have north pole N polarity, and the permanent magnet asymmetric systems and methods will function substantially the same as disclosed herein.
- the permanent magnets may differ in shape and type.
- the cylindrical magnets may be cylinders and/or cylinders with a central bore or hole defined therein in a longitudinal direction of the cylindrical magnet(s).
- the magnets may be provided with blind bores.
- Magnets may be configured with the necessary central bore and/or blind bores for enhancing the magnetic fields thereof or generating the desired magnetic fields thereof.
- Other magnet shapes such as rectangular magnets or flat magnets, may have transverse (through the thickness) bores or holes or blind bores for enhancement or desired magnetic field
- any given permanent magnet described herein may comprise a plurality of smaller permanent magnets that are stacked together to perform the same function and polarity as the given permanent magnet, if desired.
