Hi to all,

Attached a simple magnet model

what i want to do is to define:

magnetic field:
Hy = 10*sin(2*pi*freq*t)[A/m]

and to see the result in time domain maybe by 1D graph or even to see the streamlines changing in time

is it possible?

how should i define this magnetic field to act like this on this magnet?

Best regards,
Arye

A permanent magnet with a self varying magnetic field is a strange idea but here is an option.
