Elctromagnetic induction by a solenoid moving with the speed of light??
The moment the magnetic field is generated, it should take some time to reach some distance. It cannot reach infinity instantly, it should have some speed, and that speed cannot be more than that of light. So let’s say that the newly generated magnetic field, through a current carrying wire, travels with the speed of light. Now for the application of the faraday’s law, let’s bring a magnet near a solenoid, through which initially no current flows, and make the magnet move with the speed of light. Will there be electromagnetic induction observed in this case?
Take another case, when instead of a magnet we have a different circuit containing a solenoid through which current flows when the switch is made on, and this circuit is held stationary moving the other one with the speed of light. Will there be electromagnetic induction observed in this case? What I think is that, as the system without current is moving as fast as the magnetic field … it never gets the chance to cut the magnetic field and cause induction to occur in the solenoid. So there should be no induction. But there is relative motion between the two systems and (also there is NO time varying magnetic field through the moving solenoid,)AND no induced current will be produced ...
so will the induction take place or not...??
if induction does not take place then the principle or relativity goes wrong...
