A coil is placed in a magnetic field B as shown below : A current is induced in the coil because B is :
Select the correct option:
A
Outward and decreasing with time
B
Parallel to the plane of coil and decreasing with time
C
Outward and increasing with time
D
Parallel to the plane of coil and increasing with time
✓ Correct! Well done.

Solution
$
\overrightarrow{\mathrm{B}}
$ must not be parallel to the plane of coil for non zero flux and according to lenz law if B is outward it should be decreasing for anticlockwise induced current.-
