Answer:
Materials required: 1) Battery 2)switch 3) (iron nail(nearly 8cm) 4)insulate copper wire (50cm). and small pins.
procedure: Take an iron nail and wound the insulated copper wire tightly around the nail works as a coil.the two ends of the coiled copper wire are connected to a battery and a switch in series connection as shown. (switch must be in the OFF position)place some pins near the iron nail and switch ON the circuit.
observation: we observe that ,when we switched on the circuit, all pins cling to the end of the iron nail. this indicates that coiled copper wire around the nail acts as a magnet when electricity passes through it. it means the coiled copper wire around the nail acts as an electromagnet .
