Powerful Ring Rare Earth Magnets N42 , Gold Coating High Energy Large Ring Magnets

This ring neodymium magnet is widely used in genetors, motors, IT products, Nuclear Magnetic Resonance, speaker and other products. Neodymium magnet is easily rust and oxidated, so their surface must be plated Zn, Ni, Silver, Gold or made phosphor and epoxy treatment.

NdFeB magnets are mainly composed of neodymium(32%), iron(64%), boron(1%), and a few quantity rare earth material, such as Dy, Tb, Co, Nb, Ga, Al, Cu,etc.Neodymium magnet (Nd-Fe-B) is one of the highest property and strongest permanent magnet by now, are made through powder metallurgy manufacturing techniques. Especially its application in motors makes products miniaturization and micromation.

★ How to shield the magnetic field?

Normally, we use the iron sheet to shield the magnetic field. The iron sheet must be thick enough, otherwise, its saturated magnetization will only shield parts of magnetic field. So it’s very necessary and important to choose the high permeability materials and its suitable size and dimensions, so that the magnetic leakage can be less.
