photons are trapped in the magnetic field when the photon hits the electron of the copper coil the photon take the spot of the electron , its free to move . Answer2: The induced current is a...
There are magnetic fields around a magnet that form closed loops. Although you can't see these fields there existence can be observed by taking two magnets and seeing that they pull themselves...
When a bar magnet is thrust into a coil, the magnetic field of the magnet will "sweep" across the wire in the coil and induce a voltage in that coil. This is called induction, and if the coil is...
