Magnet FAQ

What is electroplated on the surface of the magnet for better conductivity?

It is said that magnet can conduct electricity? So which magnets can conduct electricity? What kind of magnet cannot conduct electricity? What's the principle? Here are some examples of magnets that can conduct electricity.
Magnet, although the name contains the word "iron", but, in fact, magnet does not belong to iron, each material contained in the material composition is not the same, in terms of the physical properties of the magnet - conductive properties. Different kinds of magnets have different conductivity.
We know that magnets include: ndfeb strong magnets, permanent magnet ferrite magnets, samarium-cobalt magnets, aluminium-nickel-cobalt magnets, and iron-chromium-cobalt magnets.
However, among the five categories of magnets, not all can conduct electricity, such as ferrite magnets can not conduct electricity, the other four kinds of magnets can conduct electricity, but the conductivity depends on the composition of the magnet itself each time.
Which magnet conducts electricity better?
Galvanized neodymium iron boron arc
Sintered ferrite generally does not conduct electricity, the magnetic steel of neodymium iron boron generally conducts electricity, iron nickel cobalt conducts electricity well. When the surface of ndfeb magnet is electroplated with nicuni, its conductivity is better.
