2. When current is stopped from flowing in the coil of wire, the iron nail no longer remains a magnet. Since the iron nail loses its magnetism, therefore, the steel pins do not cling to it anymore.
3. Answer. some devices where magnetic effect of electric current is used are Electric BELL,Crane,Motor and Loudspeaker.
4. When the switch is on, the circuit is completed and current flows. The electromagnet becomes magnetised and hence attracts the soft-iron armature and at the same time pull the hammer to strike the gong. This enables the hammer to strike the gong.
