Simulating Magnetic/Electric Fields: Is It Possible?

[ShayanJ]

Is there a simulation software capable of simulating the effects of magnetic and electric fields like the current iduced in a loop because of a changing flux?
thanks

I don't know what level of precision you're wanting, but there is a nice variety at http://www.falstad.com/mathphysics.html

I want sth like catia or solidwrork but capable of showing that eg. if we have a conductor loop which is in a changing magnetic field,how will be its current.
