Question 17 • OR-Science 8

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

Answer
A
It induces a current.
B
It stops the current.
C
It becomes a magnet.
D
It loses its magnetism.

Explanation

When electric current flows through a solenoid, it produces a magnetic field. Placing an iron bar inside the coils causes the iron to become magnetized by that field, so it acts as a magnet. It does not induce a current just by being placed there.
