Expert Answer

Step 1

 

According to Lenz’s law, the induced EMF due to change in magnetic field through a coil opposes its cause of induction.

Step 2

a)

In this case, due to motion of rod the magnetic flux through the coil changes such that the magnetic field linked through the coil decreases in magnitude out of the plane. So current will try to produce a field in outward direction and the current will be anti-clockwise.

Step 3

b)

Magnetic flux linked through a coil decreases with time, so the coil current wi...
