how do we show the magnetic field lines, in a AC current solenoid?

Question

if the direction of the current keeps changing ( ac), then the direction of the magnetic field keeps changing with the same frequency! .. thats all i know :P

anonymous · Answer

you can't draw it.. these fields are a function of time.. are you asking me a graph of field vs time?

anonymous · Answer

nope the paterns? of field lines
