Two loops of wire are arranged so that a changing current in one,the primary,will induce a current in the other,the secondary.The secondary loop has twice as many turns as the primary loop.The current in the primary at this moment is 3 A and increasing.The current in the secondary must be
A)3 A.
B)6 A.
C)zero.
D)There is insufficient information to work this problem.

The question provides information about the number of turns in each loop and the current in the primary loop but does not specify the rate at which the current in the primary loop is changing (i.e., the rate of change of current or the magnetic flux), nor does it provide information about the resistance or other characteristics of the loops that would allow us to calculate the induced current in the secondary loop. Therefore, there is insufficient information to determine the induced current in the secondary loop.
