Question

What happens to an iron bar when it is placed within the coils of a solenoid?

It induces a current.
It stops the current.
It becomes a magnet.
It loses its magnetism.

Answer 1

When an iron bar is placed within the coils of a solenoid, it becomes a magnet.

Answer 2

The correct answer is option C. It becomes a magnet

Step-by-step explanation:

A solenoid is a cylindrical coil wound from a wire. When an electric current is passed through the solenoid, a magnetic flux is produced around the solenoid. This magnetic flux is equally distributed inside the solenoid and whenever a metal like iron is placed in the path of these magnetic lines of force, the metal becomes a magnet which in the given case is iron.
