Question

How can 2 be correct if 1 is correct?
We apply Lenz's law: The change in magnetic flux must be opposed by the induced magnetic field.

1- At position number 1 the magnetic field caused by the wire is directed out of the paper. The coil is moving into an area of greater magnetic field and closer to the wire. Thus, the flux through the coil is increasing. According to Lenz's law this increase must be countered by the induced field. The direction of the induced field as a result goes into the paper. So, the current in the coil is clockwise.

2- At position number 2 the magnetic field is going into the paper and decreasing as the coil is moving away from the wire. Again, according to Lenz's law the induced magnetic field must counter. Thus the induced field must go into the paper. As a result the current in the coil is clockwise in this case also.

Explanation / Answer

according to lenz's law E =- / t the direction of current obey the right hand law so no matter how the direction of field is the current in the coil is clockwise
