I.
The direction of induced current in a coil is simply decided by using lenz law which states that cause oppose the effect
Now as the current is going upward and is decreasing so that due to this the magnetic field of this wire is come upward in the loop A so that due to this Loop will try to induce current in such a way that it will try to reduce the effect of this upward magnetic field hence in this loop the direction of induced current will be in clockwise direction .
Similarly in the loop B the direction of wires magnetic filed is into the page or in downward direction so that due to this the current induced in this loop is in anticlockwise direction.
II.
Since induced current dependency is solely on the magnetic field imparted on it and the area of the loop so that here as the loop B has higher area so that induced current will also be higher in loop B as compared to the loop A.

An decreasing current I flows in an elliptical loop of wire. Two
loops of wire are placed as shown. Why is the flow of induced
current counterclockwise for loop 1? I thought that mutually
induced emf equals (-)M(di/dt). Doesn't the negative sign mean that
the mutually induced emf (and hence the induced current) will be in
the opposite direction of the rate of change of current? So why
wouldn't the induced current for loop 1 be clockwise?

The current I in a long, straight wire is constant and is directed toward the right as in (Figure 1). Conducting loops A, B, C, and D are moving, in the directions shown, near the wire. Part A For each loop, is the direction of the induced current clockwise or counterclockwise, or is the induced current zero? Drag the appropriate items to their respective bins. Part B For each loop, what is the direction of the net force that the wire exerts on the...
