Use Lenz's law to answer the following questions Concerning the direction of induced currents. (a) What is the direction of the induced current in resistor R in Figure P31.27a when the bar magnet is moved to the left? (b) What is the direction of the current induced in the resistor R right after the switch S in, Figure P31.27b is closed? (c) What is the direction of the induced current in R when the .current Iin Figure P31.27c decreases rapidly to zero? (d) A copper bar is moved to the right while its axis is maintained perpendicularly to a magnetic field, as in Figure P31.27d. If the top of the bar becomes posi- tive relative to the bottom, what is the direction of the magnetic field? R (a) (ъ) R (c) (d)
