Question

A square loop of wire is pulled to the left (at a constant speed) away from a long straight vertical wire with current directed upwards as shown in the diagram. What describes the current induced in the loop? Describe the direction of the magnetic force on the loop due to the long straight vertical wire. If the loop was being pulled straight up (but still on the LEFT side of the long straight wire) and pulled slower than above, how would the induced current in the loop compare to the above situation (at the moment the loop is in the same location as above)?

Explanation / Answer

13) d (as loop tries to increase the decreasing flux)

14) a (F = i(l x B))

15) e (as there is no change in flux in this situation)
