Electromagnetic Induction

Question:

The magnitude of electric current is increasing from A towards B. If there is any induced current in the loop as shown in the figure, its direction will be:

Options:

Clockwise

Anticlockwise

No induced current

Can not be predicted

Correct Answer:

Clockwise

Explanation:

The correct answer is Option (1) → Clockwise

Emf generated due to magnetic flux,

$emf=-\frac{d\phi}{dt}$ [$\frac{d}{dt}=+ve$ ($\phi$ is increasing)]

and,

Since $ε$ is -ve, the current flow clockwise.
