Trapezoidal NdFeB Magnet

As we all know, naturally, permanent magnet has two poles: N and S. But, however, there are some occasions that need one-pole magnet, that is, magnetism on only one side of the magnets, or else, the magnetism on one side will disturb the other side, or damage the product, or useless to the product. Thus, the one-side magnet can save cost and also magnetic material.

Product Description

Trapezoidal NdFeB Magnet

 

As we all know, naturally, permanent magnet has two poles: N and S. But, however, there are some occasions that need one-pole magnet, that is, magnetism on only one side of the magnets, or else, the magnetism on one side will disturb the other side, or damage the product, or useless to the product. Thus, the one-side magnet can save cost and also magnetic material.

Generally, there are no real such  permanent magnets  in the world, but we can wrap one side of the magnet by special treated galvanized steel, thus the magnetism of this side can be shielded and refracted to the other side, which make the magnetism concentrate on one side.

Just like the refraction of satellite dish to signals and torch dish to light, the effect of galvanized steel to magnetism is also the same, and mainly determined by the following three factors:

1.    Material: the types and thickness of the material, and the distance between magnet and the material have great influence to the refraction effect. Currently, there are no material can shield magnetism completely, and galvanized steel is a good choice.

2.    Angle: according to the refraction theory, arc-shaped material has better effect rather than right-angled, thus the one-side magnet always consists of arc-shape steel and neodymium disc magnets.
