A coil is placed in a magnetic field $\vec{B}$ as shown below :

A current is induced in the coil because $\vec{B}$ is :

Options:

Answer:

Solution:

Lenz's law state that the direction of the induced current is such that it opposes its cause of generation, so,

$\vec{B}$ , must not be parallel to the plane of coil for non-zero flux and according to Lenz's law if $B$ is outward it should be decreasing for anticlockwise induced current.
