Question:

1. A square loop moves to the right from an area where B = 0 completely through a region containing a uniform magnetic field directed into the page (Fig. 21-52), and then out to B = 0 after point L. A current is induced in the loop
(a) Only as it passes line J.
(b) Only as it passes line K.
(c) Only as it passes line L.
(d) As it passes line J or line L.
(e) As it passes all three lines.

2. Two loops of wire are moving in the vicinity of a very long straight wire carrying a steady current (Fig. 21-53). Find the direction of the induced current in each loop.
For C:
(a) Clockwise.
(b) Counterclockwise.
(c) Zero.
(d) Alternating (ac).
For D:
(a) Clockwise.
(b) Counterclockwise.
(c) Zero.
(d) Alternating (ac).
