Several Conceptions You Need to Know About Magnetic Products

Permanent magnets can be natural products, also known as lodestone, and man-made one with neodymium iron boron as the famous representative which have a strong magnetic field.

Non-permanent magnets

After being heated to a certain temperature, the magnetism of Non-permanent magnets would suddenly disappear. During this process, all magnet molecules in magnets are changed from ordered to unordered.

If put the magnets which have lost magnetism into the magnetic field, when the magnetization strength reaches a certain value, they would have magnetism again. Magnet molecules are changed from unordered to order.

Man-made magnets

Man-made magnets can be divided into horseshoe magnet and bar magnet, both of which are so common in our daily life. Compared with a bar magnet, horseshoe magnets are more popular. What single side magnet is that one side has magnetism while the other side only has weaker magnetism? How to change common magnets into a single side magnet?

It is so simple, just put a galvanized iron deal with special ways on one side of the common magnet, the magnetism on this side would be shielded while on the other side the magnetism would become stronger. In many cases, single side magnets are needed because it can reduce costing and economize magnetic materials.

Diamagnetic

Diamagnetic materials are some types of anti-magnetic materials. When putting them in the magnetic field, they have produced a weak repulsive force to the magnetic force.

Paramagnetic

Paramagnetic refers to a material's magnetic state. Some materials may be influenced by the external magnetic fields to produce the same direction quantity of magnetism. Such material has a positive magnetic susceptibility. The opposite conception of paramagnetic is anti-magnetic.
