A current is induced in the coil because $$\overrightarrow B $$ is :
A current is induced in the coil because $$\overrightarrow B $$ is :
Outward and decreasing with time
Parallel to the plane of coil and decreasing with time
Outward and increasing with time
Parallel to the plane of coil and increasing with time
Explanation
$$\overrightarrow B $$ 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.
