g A square loop of wire sits flat on the xy plane in a magnetic field which is pointed in the positive z direction. When viewed from above, which way will current flow in the loop if the magnetic field starts to decrease in magnitude?

Answer:

clockwise

Explanation:

Due to Lenz's law

[tex]\epsilon=-\frac{d\Phi_B}{dt}[/tex]

we know that the magnetic flux generated by the induced current is opposite to the principal magnetic flux. Hence, if the magnetic flux is increasing the current has a clockwise direction. If the magnetic flux is decreasing the induced current has a counterclockwise direction.

In this case the current flow has a clockwise direction.

hope this helps!!
