FAQ

1, Why are neodymium magnets coated?
Neodymium magnet are mainly a composition of neodymium, iron and boron. When the magnets are exposed to air,the iron in the magnet can rust and ruin the magnet, because iron is easy to be oxidized. Thus, to prevent the magnet from corrosion, the magnet have to be coated.

2, What type of coating can you supply?
We can supply the type of Nickel, Zinc,Epoxy,Gold,Silver,Sn,Parylene.

3, Which is the strongest type of magnet?
Neodymium(NdFeB) magnets are the strongest magnet in the world.

4,Can you supply monopole magnet?
No,we can't. No one can supply monopole magnet, because it doesn't exist, all magnets must have at least two poles.

5,What is Maximum Operating Temperature?
It is the temperature at which the magnet begin losing its ferromagnetic ability.

6,What is Curie Temperature?
It is the temperature at which the magnet will lose 100% of its ferromagnetic ability.

7,Will neodymium magnet lose their strength with time?
No, the magnet will keep the strength lifetime.

8, How is the strength of a magnet measured?
Gaussmeters are used to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss. Sometimes it measured in Tesla. Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate.

9, Is one pole stronger than the other?
No, both poles are with the same strength.

10, How to identify the pole of a magnet?
You can use a compass, or an already identified pole of another magnet.
