Electromagnetic Induction states that moving a magnet through a loop of wire creates which of the following? a electric current b magnetic field c magnetic pole d magnetic domain
Electric current
a electric current
Any kind of changing magnetic field on a conductor produces a current. To change the magnetic field you can either move the magnet in or out of the loop or you can change the size of the loop.
The direction that the magnet is moving will decide which direction the current is moving in the loop, so pulling the magnet in and pulling it out will cause the electric current to flow in one way and the other way going backwards and it's dependent upon whether you have the north or south pole.
Electric current because of lenz's law - a change in magnetic flux will induce an emf in the conductor which creates its own magnetic field that opposes the magnetic field that created it.
