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.
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

Sm2Co17, 28-30MGoe, super high performance, working temperature:350 Celsius degree
SmCo magnet is a high performance, low temperature coefficient permanent magnet made of samarium and cobalt and other rare-earth elements. Its biggest advantage is its high working temperature---350 Celsius degree , It needn't to be coated because it is difficult to be eroded and oxidized. SmCo magnet is widely used in motors, watch, transducers, instruments, positional detector, generators, radar and other applications.
