Quick Question about magnetic induction (1 Viewer)

[bunsniper]

Hi, i'm fairly new to this forum and i'm just stumped of this question for a while know.

consider:
a horizontal solenoid without the soft iron core is connected to a galvanometer
a magnet is travelling from left to right into the solenoid
during its travel INSIDE the solenoid, will there be an induced current?

Thank you guys!

HMMMMMMMMMMM...omgdns.. thats a tricky question T.T but essentially when u pass a magnet through a solenoid, the sheer complexity of the electron interactions will open up a blackhole leading into the netherdimensions of space. Hope that helps = ) (P.S. this is not jack... or is it ><) AHGAHADFHAEDFY%EWSADWT$

Assuming constant velocity, I think while inside the solenoid, there will be no current induced, but while entering the solenoid and leaving it, there will be induced EMF as there is a change in rate of magnetic flux.

Just a guess.

xGhanem is right, except a current will be induced while within the coils of the solenoid. As long as there is relative movement between the solenoid and magnet (i.e. a change in magnetic flux), then a current will be induced according to Faraday's Law. The induced current will be directed so as to oppose the original change in flux that induced it, according to Lenz's Law.
