Question

Describe briefly how an iron rod can be magnetised using the electrical method

Answer 1

The process by which an iron rod can be magnetized using the electrical method is called solenoid.

• To magnetize a rod permanently, we should wrap a coil around the iron rod.
• Then we need to connect the two ends of the wire to the two ends of the battery.
• This will create the flow of electrons from one end of the rod to the other. The electrons will align and will create a north pole and south poe in the rod.
