differences between linear & nonlinear magnets

[janas21]

Hello,

I would like to ask which are the main differences and with which criteria, except the economic and the field we want to have,we choose either linear or non-linear magnets? Typically this things are provided by the magnet companies without any explanation.


or is there any recommendation web sites explain these differences?

Thanks in advance

What do you mean by linear/nonlinear?

janas21:
I'm guessing you mean a material with a linear/nonlinear 2nd quadrant BH curve.

One does not choose whether to use a linear or non-linear magnet, that's how a particular material behaves. As an engineer, you choose which material will perform the way you want (as long as economics allow).

This is a fundamental property of magnetic materials.
