If the current in the loop of the attachment were halved, the total flux threading the loop would:

1) Halve
2) Be reduced to 1/4 of the previous value
3) Decrease to 3/4 of its original value
4) Decrease by more than 1/2 but greater than 1/4 its previous value.

Induced Current in the Specified Loop

See the attached file.
Three loops of wire are located near a long straight current-carrying wire, as shown in the attachment. Indicate below the direction of the induced current in the specified loop, depending on the action described relating to the current in the wire or the motion of the loops. Please explain your answer.

1. If the current in the wire is constant, but Loop A is moving away from the wire, the induced current in Loop A will be:

2. If the current in the wire is decreasing, the induced current in Loop C will be:

3. If the current in the wire is constant, the induced current in Loop B will be:

4. If the current in the wire is decreasing, the induced current in Loop A will be:

5. If the current in the wire is constant, but Loop C is moving to the left, the induced current in Loop C will be:?
