Question

Calculate the resulting average emf induced in the coil.

A 52-turn coil with an area of 3.4 X10 m2 is dropped from a position where B = 0.00 T to a new position
where B = 0.25 T. If the displacement occurs in 0.35 s, and the area of the coil is perpendicular to the magnetic
field lines, what is the resulting average emf induced in the coil?
