Question

A soft iron bar is introduced inside a current carrying solenoid. The magnetic field inside the solenoid

Choose the correct answer:

a)  Will increase
b)  Will remain unaffected
c) Will become zero
d)  Will decrease

Answer 1

Answer:the answer is will increase.

Explanation:

Iron is highly ferromagnetic material. Hence, it allows maximum number of field lines to pass through it.

When current carrying solenoid is taken, it produces its own magnetic field inside and outside the solenoid.

When a soft iron bar/core is placed inside the solenoid, it magnetizes the iron bar thereby increasing the strength of the magnetic field inside the solenoid.
