What is the average emf induced in a circular wedding ring of diameter 2.3 cm if the ring is at the center of the mri magnet coils and the original magnetic field is perpendicular to the plane that is encircled by the ring?

Answer: The average emf induced by the circular wedding ring is 0.0529v.

Explanation: Diameter of ring is 2.3cm = 0.023m

Area will be πD^2/4 = 0.0529π

Since magnetic field is perpendicular to the plane encircled by the ring, it means that emf generated since time and number of turns are not considered in the question will be 0.0529π/ (π/2) = 0.0529V.
