A current is generated only when the magnet is moving. The current stops if the magnet stops moving - even if it is inside the coil. The current goes the other way if the magnet moves in the opposite direction To make the current greater: * use more coils * move the magnet faster * use a stronger magnet The magnetic field goes around each loop of wire in the coil, so if you increase the number of coils there are more places where the magnetism...
