In the diagram below, the long straight wire carries a current to the right and the current is increasing with time. This changing current produces an emf in the circular loop. What is the direction of the induced emf?
a. Clockwise b. Counterclockwise. c. We need to know the resistance of the loop
Homework Answers
We know that the direction of induced emf is in such way that it opposes the cause i.e its direction is opposite to the direction of current by which it is produced. Thus from figure it is clear that horizontal current is directed in right direction therefore the direction of induced emf in circular coil will be in counter clockwise direction.

a) a horizontal long straight wire carries a current of I1= 8A from left to right. The wire is tangential to a circular loop of wire of Radius R= .03 m lying immediately below it. The loop carries a current of l2= 2A in the counter clockwise direction. Assuming that the thickness of the wires are negligible, find the magnitude and direction of the net magnetic field at the center of the circular loop b) a second long wire also...
