How to Choose Permanent Magnet Materials

Each permanent magnet material discussed above has its own pros and cons. How to choose the right one for your particular application is a challenge to any user. A balance between cost and performance must be considered in selecting of permanent magnet material. Following is a Comparison Table to help you select a right permanent magnet material for your applications.

Permanent Magnet Material Comparison Table
Note: The data listed in the table are for reference only

Residual Induction (Br):
Also called "Residual Flux Density". It is the magnetic induction remaining in a saturated magnetic material after the magnetizing field has been removed.This is the point at which the hysteresis loop crosses the B axis at zero magnetizing force, and represents the maximum flux output from the given magnet material. By definition, this point occurs at zero air gap, and therefore cannot be seen in practical use of magnet materials.

Coercive Force (Hc):
The demagnetizing force, measured in Oersteds, necessary to reduce observed induction, B, to zero after the magnet has previously been brought to saturation.This value indicates the ability of magnet to keep its magnetic force unchanged.

Maximum Energy Product (BHmax):
The magnetic field strength at the point of maximum energy product of a magnetic material. The field strength of fully saturated magnetic material measured in Mega Gauss Oersteds, MGOe.

Neo IB magnet is mainly made of Neodymium, Iron and Boron, with excellent magnetic property, abundant raw material in China and reasonable prices, Neo IB can be used as an ideal magnet in mini-motor, permanent magnet instrument, electronic industry, auto industry, petro-chemical industry, nuclear magnetic resonance, sound device, magnetic suspension system, magnetic transmission machine and iatrical apparatus and etc.

Neo IB magnet surface is usually treated with some special methods to avoid corrosion, including zinc, nickel, tin, silver, gold plating, phosphate and spraying epoxy resin etc.
