I am trying to measure the eddy currents induced by a DC current after said current shuts off. I am having trouble finding a way to define a current that stops after a set amount of time, and was wondering if ANSYS has a simple way to go upon this.

I believe that a simple step function would suffice, i.e. have a current run through a wire at a value i(t) which is constant until, say t = 10s. So i(t) is a positive number for t < 10 and zero for t >= 10.

It would be great if anybody could point me in the right direction!

Thanks!
