Question

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.

Answer 1

Correct Answer - 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.
