Question

To prepare an electromagnet of the given iron nail​

Answer 1

Answer:

Aim : To make an electromagnet.

Materials Required: An iron nail, a battery, a switch, some insulated copper wire, and some iron paper pins.

Procedure: Coil the insulated copper wire around the iron nail. Connect the ends of the

cable to the battery through the switch. Close the switch so that electric current flows

through the copper wire. Now bring the iron paper pins close to the iron nail.

Observation And Conclusion: The paper pins get attracted to the nail, showing that the nail has turned into an electromagnet. Now, if you switch off the current, the iron paper pins will drop off the iron nail
