FAQ
1
Why are neodymium magnets coated?
Neodymium magnet is 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?
At present,the highest property magnets are rare earth magnets,NdFeB magnets are the strongest for rare earth magnets,but SmCo magnets are the strongest magnets for the environment over 200 degrees celsius.
4
What is monopole magnet?
All permanent magnets have two poles, but in some positions require mono pole magnet, so it is necessary to use a iron wrap one side of the magnet, the magnetism of the side that wrapped by iron is shielded, and refracted to the other side of the magnet through iron, the magnetic force of the other side is enhanced, so it called mono pole magnet or single pole magnet. There is no real single magnet!
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.
