The switch in the bottom loop of Fig. P6.1 is closed at t = 0 and then opened at a later time t1. What is the direction of the current I in the top loop (clockwise or counterclockwise) at each of these two times?
Figure P6.1 Loops of Problem 6.1.
The direction of the current
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
It is observed that at
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.
