To determine

The direction of the current I in the top loop.

Answer to Problem 1P

The current in the top loop will be in counter-clockwise direction.

Explanation of Solution

Given data:

The required diagram is drawn as shown in Figure 1.

Calculation:

The required diagram is drawn as shown in Figure 2 at t=0.

Fundamentals of Applied Electromagnetics (7th Edition), Chapter 6, Problem 1P , additional homework tip  2

It is observed that at t=0, the direction of current in the bottom loop is clockwise. Due to this current, there is an increment of flux in the secondary loop and if flux increases, then the current will also increase.

Hence, the current in the top loop is also momentarily clockwise direction.

From Figure 1, it is observed that there is no current flow in the bottom loop because switch is open. Due to this, there is a decrement of the flux in the secondary loop and if flux decreases then the direction of current will be reversed.

Hence, the current in the top loop will be in counter-clockwise direction.

Conclusion:

Therefore, the current in the top loop will be in counter-clockwise direction.
