the current in a straight conductor stretched over a magnetic needle is directed from south to north.the north pole of the needle will point towards which direction..???
Electric current can also be induced through a wire loop, by moving it near a fixed magnet. So a current is induced either by moving a magnet near the loop or by moving the loop near a magnet. It is the relative motion between the two which is important. It does not matter which of the two is moved. Thus the electromagnetic induction takes place because of the relative motion between a magnet and a coil. The induced current exists as long as there is a relative motion between the coil and the magnet.
