Hi,
I am trying to model the interaction between a permanent magnet and a coil using AC/DC module. The physics I am using is Magnetic Fields (mf). This is a time-dependent study, where the eddy current induced in a separate steel plate will be monitored, as a consequence of the interaction between the permanent magnet and the coil.
I am interested in making the permanent magnet to be stationary, while the coil to be time-dependent (supplied with a pulse). However, I fail to make the magnetisation value of the permanent magnet to not be time-dependent, i.e., the initial value of the magnetisation is always zero, as is the supplied current through the coil.
How should I initialise the magnetisation value of the permanent magnet, so that it stays constant from 0 s?
