A current carrying straight wire passes inside a triangular coil as shown in figure. The current in the wire is perpendicular to paper inwards. Find the direction of the induced current in the loop, if current in the wire is increased.

Explanation

Magnetic field lines around the current carrying wire are as shown in figure below. Since, the lines are tangential to the loop `(theta=90^(@))`, the flux passing through the loop is zero, whether the current is increased or decreased. Hence,change in flux is zero. Therefore, induced current in the loop will be zero.
