Assertion: Magnetic field `B` (shown inwards) varies with time `t` as shown. At time to induced current in the loop is clockwise

Reason : If rate of change of magnetic flux from a coil is constant, charge should flow in the coil at a constant rate.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
At time `t_0`, magnetic field is negative or and increasing.
Hence, induced current will produce `ox` magnetic field.Or induced current should to be clockwise.
If `(dphi)/(dt)=`constant. Then e=constant
`:. i` or rate of flow charge is constant.
