Question

Assertion : The strength of the magnetic field produced at the centre of current carrying circular coil increases on increasing the number of turns of the circular coil
Reason : magnetic field strength is directly proportional to the number of turns of the circular coil.

Answer 1

Both Assertion and Reason are true and R is the correct reason for A.

Hope this helps you :)

Answer 2

Both Assertion and Reason are true and the Reason is correct for the Assertion.

Explanation:

• If there is an increase in current flow in the coil then there will be a increase and increase in the number of turns to the strength of magnetic field which is been produced from the current carrying circular coil.
• As the radius of the coil is inversely proportional to that of the magnetic field which is at the center of the circular coil.
