Above-mentioned base plate (1), swivel arm (4) and holder (8) are non-ferromagnetic material, first magnet (5) is for having the magnet of symmetry magnetic pole, second magnet (6) is for having the magnet of asymmetric magnetic pole, swivel arm (4) is when being in lowering position, and first magnet (5) is relative with the magnetic pole of second magnet (6).
Above-mentioned first magnet (5) and the used material of second magnet (6) are ferromagnetism permanent magnetic material neodymium iron boron, and the basic configuration of second magnet (6) is L shaped, are bondd fixing mutually and are constituted by two blocks of magnet with 45 degree inclined-planes.
The utlity model has positive effect: this device can be used as to be demonstrated the magnetic force character of the magnet with asymmetric magnetic pole, provides experimental provision for people explore outfield.Help people's spy and show its mechanism of action, also can inspire people's magnetic field force character that this device is shown simultaneously, develop brand-new product as industrialized exploitation.
Fig. 1 is a kind of structural representation of the present utility model, and wherein first magnet and second magnet are in the state that attracts each other.
Fig. 2 is in the synoptic diagram of mutual repulsion state for two blocks of magnet among Fig. 1.
Fig. 3 is the synoptic diagram of second magnet when being in the first magnet polarity opposite location.
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment 1,
See Fig. 1,
Base plate (1) is made with slabstone.Bearing (2) is made with timber, is fixed on the base plate (1) with securing member.Axle (3) is made with brass, is located in the shaft hole of bearing (2), is rotationally connected with bearing (2).Swivel arm (4) is made by nonmagnetic aluminum alloy plate materials, and the one end is made annular snap and gone up at axle (3), fixedlys connected with axle (3), and the other end is tabular, as free end.Be fixed on the tabular free end of swivel arm (4) with first magnet (5) of 504 glue with symmetry, and the N utmost point is positioned at the outer end, the S utmost point is positioned at the inner, and its magnetic field intensity is 2520 Gausses.
Still see Fig. 1, holder (8) is made by timber, is fixed on the base plate (1) with securing member.Second magnet (6) is asymmetric magnet.Method for making is, it is the polar end with inclined-plane of miter angle that the cube magnet of two symmetries is become an one polar end with grinder buffing, wherein the polar end of a magnet polishing is the S utmost point, the polar end of another piece magnet polishing is the N utmost point, the inclined-plane is relative then, being adhesively fixed with 504 glue, to form basic configuration be the L shaped magnet with asymmetric magnetic pole, and its magnetic field intensity is 380 Gausses.Second magnet (6) is adhesively fixed on holder (8) with 504 glue, and its N utmost point is positioned at the outer end, and the S utmost point is positioned at the inner.Soft iron sheet (7) is made by electrical pure iron, and basic configuration is L shaped.At ordinary times, soft iron sheet (7) can be placed on second magnet (6), inhales on second magnet (6) because of magneticaction makes soft iron sheet (7).
Before the demonstration of this device, earlier soft iron sheet (7) is taken out, grasp the free end of swivel arm (4), let go then in the top that makes it to be positioned at second magnet (6), be allowed to condition under the effect of self gravitation to fall to second magnet (6) position, when falling to position shown in Figure 1, repel each other because of the magnetic force same sex, can not fall again.Grasp the free end of swivel arm (4) this moment, soft iron sheet (7) is placed on second magnet (6), with the gaussmeter test, the magnetic field intensity at A place, first magnet (5) lower surface still is 2520 Gausses again, and the magnetic field intensity at B place, soft iron sheet (7) upper surface then is 80 Gausses.
And then let go, under gravity and magneticaction, the free end of swivel arm (4) falls to soft iron sheet (7) rapidly, in the moment of their contacts, because first magnet (5) magnetic table density is much larger than second magnet (6), so soft iron sheet (7) is attracted by first magnet (5) at once.The magnetic table density that changes naturally and present first magnet (5) C place that this moment occurs magnetic table density between first magnet (5) and second magnet (6) simultaneously is reduced to 880 Gausses, and the magnetic table density at second magnet (6) D place is recovered the state of 80 Gauss's products at 2520 Gausses, second magnet (6) the B place at former 380 Gausses and bipolar magnetic table density product first magnet (5) A place when beginning.So the two poles of the earth moments repels, the acting force of its repulsion is greater than gravity fall and adelphotaxy power.At this moment, because of magnet (5) magnetic table density is big, so soft iron sheet (7) is held by first magnet (5), first magnet (5) drives swivel arm (4) and upwards rotates rapidly clockwise, behind position shown in Figure 2, continue to turn right rapidly, the free end of swivel arm (4) is contacted with table top.
When the thickness of soft iron sheet (7) was thicker, then attractive force was greater than repulsive force, and first magnet (5), soft iron sheet (7) and second magnet (6) attract together mutually all the time.When the very thin thickness of soft iron sheet (7), then repulsive force is greater than attractive force, and first magnet (5) is in released state with second magnet (6) and soft iron sheet (7) all the time.
See Fig. 1 to Fig. 3,
All the other are identical with embodiment 1, and difference is that holder (8) cooperates for being rotationally connected with base plate (1), and when second magnet (6) was positioned at the position of Fig. 1, mechanism was identical with embodiment 1.See Fig. 3, second magnet (6) along continuous straight runs original position Rotate 180 °, then the S utmost point is positioned at the outside, and the N utmost point is positioned at the inboard.At this moment, the effect between first magnet (5) and second magnetic support (6) is only attractive and do not have repulsive force.
Base plate also is provided with shifting chute on (1), the position of holder (8) can be determined along shifting chute, when holder departed from first magnet (5) the shown in Figure 1 position relative with the residing same sex of second magnet (6), then regardless of soft iron sheet (7) thickness, the both attracted each other.
