Acircular loop of wire lies in the plane of the paper. an increasing magnetic field points out of the paper. what is the direction of the induced current in the loop?

a. counter-clockwise then clockwise
b. clockwise then counter-clockwise
c. counter-clockwise
d. clockwise
e. there is no current induced in the loop.

Option (D)

Clockwise

Explanation:

Using Lenz's Law the current is induced in such a direction so that the magnetic field created due to the current  induced opposes the increasing external magnetic field. For this case,when the field is increasing the magnetic flux increases   and current is induced in clockwise direction (by lenz law as the induced field due to induced current has influence in  opposite direction,thereby it  reduces flux).

If the field is being decreasing,current would have been induced counter-clockwise so as to oppose the decreasing flux(as then the induced flux would be in same direction.)

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
