Acoil lies flat on a level tabletop in a region where the magnetic field vector points straight up. the magnetic field suddenly grows stronger. when viewed from above, what is the direction of the induced current in this coil as the field increases?
a. counterclockwise
b. clockwise initially, then counterclockwise before stopping
c. clockwise
d. there is no induced current in this coi

c. Clockwise

Explanation:

As per FARADAY's the rate of change in magnetic flux linked with a coil will induce EMF in the coil and this will result the induce current in the coil.

Here we know that the direction of induced current in the closed loop is in such a way that the magnetic flux due to induced current always oppose the flux due to which it is induced

So we can say that if the flux linked with the coil will increase with time then flux of induced current will be in opposite direction to oppose the increasing flux.

So here when magnetic field becomes stronger then the induced current is in such a way that will always oppose the increasing flux of magnetic field

So we will say that correct answer will be

c. Clockwise

it is b. absorbs thermal energy
