Embodiment 1

[0018] as attached figure 1 As shown, the present invention is mainly made up of permanent magnetic pole 1 and silicon steel cover 4, and the appearance shape of permanent magnetic pole 1 presents hollow cylinder shape, is formed by the permanent magnet of two hollow semi-cylindricals, one of them The hollow semi-cylindrical body is an N pole permanent magnet 2, its inner surface presents an N pole, and its outer surface presents an S pole, so its N poles all face the inner core of the permanent magnet 1, and the other hollow semi-cylindrical body is an S pole Permanent magnet 3, its inner surface presents S pole, and outer surface presents N pole, so its S pole is all towards the inner core of permanent magnetic pole 1, like this, N pole permanent magnet 2 and S pole permanent magnet 3 attract each other correspondingly. Merge into the permanent magnet pole 1 of complete hollow cylinder, the top and the bottom end of the merged permanent magnet pole 1 are all round, and the m...

Embodiment 2

[0020] Such as image 3 As shown, in this embodiment, the permanent magnet magnet pole 1 is the same as the permanent magnet magnet pole 1 of embodiment 1, and the silicon steel cover 4 is deformed into an annular shape, and 3-5 annular silicon steel covers 4 with different diameters Superimposed and fixed, the superimposed silicon steel cover 4 is fixed on the side of the permanent magnet 1 and the magnetic pole anastomosis 5 by pasting or fixing parts. In the present embodiment, the permanent magnetic pole 1 has a diameter of 12.5cm, a height of 9.4cm, and a thickness of 2.5cm. The silicon steel cover 4 is formed by stacking three silicon steel covers 4 whose diameter is larger than that of the permanent magnet 1 and whose diameter increases from inside to outside. The 4 circumferences of the inner ring silicon steel cover of the present embodiment are 75cm, the 4 circumferences of the middle ring silicon steel cover are 105cm, and the 4 circumferences of the outer ring sil...

Embodiment 3

[0022] Such as Figure 4 As shown, in this embodiment, the permanent magnet pole 1 is the same as the permanent magnet pole 1 of embodiment 1, and the silicon steel cover 4 is deformed into a cup-shaped cover shape similar to that of the permanent magnet pole 1, which only has an opening at the bottom. The inner diameter of the silicon steel cover 4 is 1-2 centimeters larger than the outer diameter of the permanent magnetic pole 1, which can completely cover the permanent magnetic pole 1. In the present embodiment, the permanent magnetic pole 1 has a diameter of 12 cm, a height of 9 cm, and a thickness of 2.5 cm. , Cup-shaped silicon steel cover 4 outer diameter 15cm, high 10cm, thick 2.9mm.

Abstract

The invention discloses a permanent magnet device for converting a conservative field into a non-conservative field. The permanent magnet device comprises a permanent magnet tent, and a silicon steelcover with an inverted-U-shaped cross section is fixed to the circular top end of the permanent magnet tent in a sticking or fixing piece fixing mode. The width of the inverted-U-shaped silicon steelcover is equal to or larger than the diameter of the round face of the permanent magnet tent, and the unfolding length of the inverted-U-shaped silicon steel cover is equal to or greater than the sumof the diameter of the circular surface of the permanent magnet tent and two-side heights of the permanent magnet tent; when the silicon steel cover is fixed in the permanent magnet tent, the symmetrical center line of the silicon steel cover coincides with the matching position of the magnet tent, the selection of the thickness of the silicon steel cover fixed by the permanent magnet tent is based on the comparison of the magnetic field intensity detected outside the symmetrical center line of the silicon steel cover and the magnetic field intensity detected outside the matching position of the magnet tent before the silicon steel cover is covered, and the magnetic field intensity is preferably reduced by 5-95 times. After the silicon steel cover is additionally arranged on the magnet tent, the weakening of the magnetic field intensity outside the anastomotic part of the magnet on the magnetic tent is achieved, the weakening value reaches 5-95 times, and the purpose of converting a conservative field into a non-conservative field is achieved.

Description

technical field [0001] The invention relates to a non-conservative field permanent magnet device, in particular to a permanent magnet device which converts a conservative field into a non-conservative field. Background technique [0002] As we all know, permanent magnets have two polarities, magnetic north pole N, magnetic south pole S, and they are still two poles (N level, S pole) after breaking. A single pole does not exist. At the same time, permanent magnets have directivity. If a permanent magnet is suspended, it will be found that its south pole points to the geographical south magnetic pole, and its north pole points to the geographical north magnetic pole. There is mutual magnetic force between the poles of permanent magnets, the magnetic poles of the same name repel each other, and the magnetic poles of different names attract each other. There is a substance around the permanent magnet that can deflect the magnetic needle. This substance is called a magnetic fie...
