Problem 5Q
Suppose you are looking along a line through the centers of two circular (but separate) wire loops, one behind the other. A battery is suddenly connected to the front loop, establishing a clockwise current. (a) Will a current be induced in the second loop? (b) If so, when does this current start? (c) When does it stop? (d) In what direction is this current? (e) Is there a force between the two loops? (f ) If so, in what direction?

ANSWER:
Solution 5Q:
a)
As you connect a battery to one of the loops suddenly, it will create an induced emf in the second loop. But we know that the battery will produce a steady current and later there will be no change in the magnetic flux through the 2nd loop. So, there will not be any current in the 2nd loop anymore.
Only for a fraction, it will have a current flowing through it.
b)
