FREE Expert Solution

Magnetic flux:

ϕB=BAcosθ where θ is the angle between B and A.

In this problem, we are going to apply Lenz's law to get the direction of the induced current.

Lenz's law: The induced electric current flows in a direction such that the current opposes the change in magnetic flux inducing it.
