Use Lenz's law to answer the following questions concerning the direction of induced currents. Express your answers in terms of the letter la R R R (a) What is the direction of the induced current in the resistor R in Figure a when the bar magnet is moved to the left? O a to b O b to a O The magnitude is zero. (b) What is the direction of the current induced in the resistor R after the switch S in Figure b is closed? O a to b O b to a O The magnitude is zero. (c) What is the direction of the induced current in the resistor R when the current I in Figure c decreases rapidly to zero? O a to b O b to a O The magnitude is zero.
