Abstract

The invention deals with a compass and methods to detect the spatial direction of the predominant amount of free magnetic flux. The invention declares that it can be implemented by PMs (6, 7) on a flat plane with the possibility of rotation in three basic ways. In the first way, two PMs are used and they are rotated mechanically by 180° toward the main Earth's magnetic north. The second method implements two PMs where a freely moving PM is mechanically turned away by 180° from the main magnetic north and the fixed PM is simultaneously turned by 180° toward the main magnetic north. The third way uses 3 PMs, one movable PM (7) and one fixed PM (6) and their so-called mechanical 180°C turn to the Earth's main magnetic north and a simultaneous 180° turn of the other movable PM away from the Earth's main magnetic north.

Description

Compass and Methods for Detection of Free Magnetic Flux Technical Field

The present invention describes the detection of the direction of free inflow of magnetic flux in space by changing the magnetic shielding of permanent magnets (hereinafter P s), a major component of the compass.

Prior Art

The hitherto compasses with a magnetic latch only show the direction of the magnetic meridians of the Earth, they cannot be used to directly determine the direction of the free inflow of magnetic flux in space.

Invention Summary

The essence of the present invention is that the mechanical rotation of a horizontal plane by 180° with suitably located PMs that can change their own magnetic shielding can be used to reliably detect the direction of the prevailing inflow of free magnetic energy.

Current magnetic compasses used around the globe only show the direction of the magnetic meridian and cannot be used to determine the spatial direction of the prevailing inflow of free magnetic energy, nor can they show that the positive (+) PM is the input of magnetic flux, and negative (-) PM is the output.

On a flat horizontal surface aligned in the direction of the Earth' s magnetic meridian and made of a material with low magnetic activity, we place two NdFeB PMs, one with the

dimensions of 4 mm x 4 mm x 4 mm, and the other with dimensions of mm x 4 mm x 2 mm. The 4 mm x 4 mm x 4 mm NdFeB PM is placed with its magnetic north against the magnetic north of the Earth, and attached to the horizontal surface with adhesive tape. The 4 mm x 4 mm x 2 mm NdFeB PM is placed about 50 mm away from the previous magnet in the direction of the same magnetic meridian towards the Earth's magnetic south, and its magnetic north, i.e. one of its 4 mm x 4 mm sides, running perpendicular to the

Earth. This magnet is left lying freely. When we begin to rotate the- horizontal plane with such arranged PMs horizontally, the 4 mm x 4 mm x 2 mm PM will be lifted at an angle - it will rotate toward the 4 mm x 4 mm x 4 mm PM, and upon turning the

horizontal plane by 180°, it will be lifted up to the maximum extent. If no lift occurs, the 4 mm x 4 mm x 2 mm PM must be placed closer to the attached 4 mm x 4 mm x 4 mm PM and the 180° rotation repeated a couple of times to achieve a reliable lift and_^ return to the horizontal position. If the lift is excessive and the PM is flipped or attracted to the 4 mm x 4 mm x 4 mm PM, the 4 mm x 4 mm x 2 mm PM must be placed further away.

The above also applies in a mirror image, only the PM poles must be swapped.

In addition to these two methods, the compass can detect the direction of the prevailing free inflow of magnetic flux in space in both ways simultaneously.

The fact that the 4 mm x 4 mm x 2 mm NdFeB PM is lifted after a 180° rotation of the horizontal plane and remains standing on its outer edge is evidence that the positive PM is an entry point for magnetic energy because the PM pointed with its magnetic plus at the Earth' s main magnetic north has higher performance. However, when turned against the Earth's magnetic north, the PM shades itself magnetically, resulting in its lower performance .

It should be noted that the measurements and/or detection of the direction of prevailing free inflow of magnetic flux in space should not be performed in the immediate vicinity of foreign magnetic fields. We should also make sure to construct such compasses, with the exception of PMs, only from materials with low magnetic activity. We also have to note that some materials exhibit increased magnetic activity when subject to friction.

Brief Description of Drawings

Fig. 1 and Fig. 2 illustrate the principle in which the 4 mm x 4 mm x 4 mm NdFeB PM is positioned with its magnetic north against the Earth's magnetic north. The 4 mm x 4 mm x 2 mm NdFeB PM is placed freely, it is approximately 50 mm away from the first magnet, facing the Earth' s main magnetic south, and its magnetic north is perpendicular to the ground. Their mutual attraction or repulsion is not displayed.

Fig. 3 and Fig. 4 illustrate that by turning the plane by 180° the 4 mm x 4 mm x 2 mm PM is lifted obliquely and remains standing on its outer edge, which shows that the 4 mm x 4 mm x 4 mm PM is turned with its south pole against the Earth' s main magnetic north and thus has a higher performance. This also applies to the 4 mm x 4 mm x 2 mm PM.

Fig. 5 to Fig. 8 illustrate the mirror image of Figs 1 to 4, only with reversed magnetic poles in the PMs. Fig. 9 to Fig. 12 illustrate both above-mentioned methods simultaneously .

Fig. 13 and 14 represent the embodiment of the invention. Both PMs are obviated by 180° from the Earth's main magnetic north.

Sample Embodiment of Invention

The compass to detect the direction of free inflow of magnetic flux by changing its own magnetic shielding of PMs can be constructed by first detecting the magnetic meridian of the Earth using a normal compass or with the assistance of a PM rod suspended on a string. Subsequently, we horizontally align the plastic compass body (1) with sliding mounts on a ruler (2, 3) with external dimensions of 140 mm x 27 mm x mm 17 in the direction of the previously detected Earth's magnetic meridian. One sliding segment made of plastic with a h = 5 mm, w = 6. mm, 1 = 6 mm stand (9) and a top groove (4) measuring h = 2 mm, w = 4 mm, 1 = 4 mm is stabilized in the middle of the ruler, and a NdFeB PM (6) measuring 4 mm x 4 mm x 4 mm is inserted into the groove so that its magnetic north is placed against the Earth's magnetic north. The second NdFeB PM (7) with the dimensions of 4 mm x 4 mm x 2 mm, is placed with its magnetic north (i.e. one of its 4 mm x 4 mm sides) on the second sliding segment (3) which must be oriented towards the Earth's magnetic south and its base (5) dimensions are h = 3 mm, w = 6 mm, 1 = 6 mm, about 50 mm from the first segment size and perpendicular to the Earth, but allowing 90 ° vertical rotation without side shift. To do this, we use a non-ferromagnetic needle-shaped metal axle (10) with two tips, made of e.g. titanium (6AL 7V) ,' stainless steel etc., and measuring 7 mm x 0.5 mm, attached to the 4 mm x 4 mm x 2 mm NdFeB PM on the bottom of its 4 mm x 2 mm outer side using metal adhesive or a clip with the possibility moving the axle upwards. To mount the axle, we use a sleeve (8), for example made of stainless steel 1 mm thick, with internal dimensions h = 3 mm, w = 6 mm, 1 = 6 mm, and extended on the top by 1 mm in the axle area, with 0.5 mm depressions. To emphasize the oblique stroke, a hard and light tongue can be glued to the moving PM, e.g. made of^' plastic, in the shape of a transversely cut magnet (11) so as to protrude 15 mm, directed to the 4 mm x 4 mm x 4 mm NdFeB PM. The PM on the sliding segment located in compass corpus grooves (12) is moved closer to the PM on the stabilized segment up to the distance in which any more approaching would result in lifting the moving PM. Given the PMs used in this case, the thickness of the axle, its location to the center of gravity, as well as the tongue weight at the PM, the mutual distance from the inner sides of the PM is approximately 41 mm.

It is commonly known that the intensity of magnetic flux differs in space, therefore, differences in the measurement can be observed.

If we begin to rotate the compass horizontally, the 4 mm x 4 mm x 2 mm NdFeB PM will lift at an angle and rotate around the axle. After turning the compass 180° degrees, the 4 mm x 4 mm x 2 mm NdFeB PM is lifted obliquely to an angle of about 45 degrees and it remains lifted.

The above also applies in mirror image, however, one needs to be mindful that after the 180° mechanical turn of the moving 4 mm x 4 mm x 2 mm NdFeB PM from the Earth' s main magnetic north, the magnet is moved into the space with different ratios for magnetic flux compared with the first case, and will not be reliably lifted and returned to the horizontal position.

Therefore, in addition to changing the PM polarity, we must also move its the center of gravity, that means that the axle will be moved upwards along the side of the 4 mm x 4 mm x 2 mm PM. At the. same time we must also move the axle mounting areas, i.e. the sleeve with axle will be moved upwards so that the 4 mm x 4 mm x 2 mm NdFeB PM remains horizontal even after the adjustment of the center of gravity on the base with its 4 mm x 4 mm wall. It is obvious from the above that a PM which is firmly fixed to the axle, for example using a metal adhesive, is not useful on both sides.

Industrial use

In addition to the existing compasses with horizontally rotating magnets, which only show the direction of the magnetic meridian of the Earth, it is also necessary to make use of compasses that can, by changing their own magnetic shielding, reliably detected the direction of incoming prevailing free magnetic energy.

Since the transformation of free energy is not the subject of the present invention, we consider the description of the invention to be sufficient.
