linear / non-linear magnets and orientation of magnetization

linear / non-linear magnets and orientation of magnetization

linear / non-linear magnets and orientation of magnetization

(OP)
Hello,

 I would like to ask a question, I have searched in biography, also in papers but up to now I can not find any answer.

I am trying to model a relative big magnet, let say 10 mm rectangular shaped and with a magnetization direction forming an angle of 10 degrees regardless the horizon (x-axis).

For such a structures ( inclined magnetization) is it play a critical role if we select a linear or a non-linear type of magnet? For instance i have a Alnico 500 (non-linear) and i want to see if it is possible to have such a magnet such a magnetization direction

Thanks in advance

RE: linear / non-linear magnets and orientation of magnetization

Self-demagnetization from the shape of the magnet can become an issue in the case you describe.  Alnico 5 (not sure what you mean by 500) is particularly sensitive to that.

You'll be better off using a high coercivity material such as SmCo & NdFeB.  The fact that their magnetization curves are mostly linear is not nearly as important as the high coercivity (which will provide resistance against demagnetization).

It is possible to have such a magnet, one method would take a block magnet and fabricate it so that the final shape is aligned 10 degrees the magnetization axis.
