Question

Which of the following can result in the increase in the strength of a solenoid?

• A. The number of turns of the solenoid is increased.
• B. The current passing through the coil is increased
• C. The length of the solenoid is increased.
• D. Both A and B

Answer 1

Answer: (A), (B), (D)

The correct options are
A

The number of turns of the solenoid is increased.

B

The current passing through the coil is increased

D

Both A and B

The strength of the solenoid can be increased by increasing the number of turns and by increasing the current flowing through it. Introducing a soft iron core also increases the strength of the solenoid.
