Explanation / Answer

part A)

for the current in the winding is increasing and it is from a to b

Using Lenz's law , the current in the coil containing R will oppose the applied field.

The induced current in the resistor R is directed from right to left

part B)

the current in winding A is directed from b to a and is decreasing

Using Lenz's law , the current in the coil containing R will be in same the applied field.

The induced current in the resistor R is directed from left to right.

c)

the current in winding A is directed from b to a and is increasing

Using Lenz's law , the current in the coil containing R will oppose the applied field.

The induced current in the resistor R is directed from left to right.
