Question

Determine the direction (right, left or zero) of the current induced to flow through the resistor in the circuit containing the secondary coil. The coils are wrapped around a plastic core.

Part A: Immediately after the switch is closed (Figure 1) in which direction does the current flow through the resistor?

Part B: If the switch is then opened (Figure 2) in which direction does the current flow through the resistor?

Part C: Immediately after the switch is closed (Figure 3) in which direction does the current flow through the resistor?

Part D: If the circuit containing the battery moves to the left (Figure 4) in which direction does the current flow through the resistor?
