Question

Consider an electromagnet capable of producing a maximum magnetic field of (2.50+A) T. A circular loop of wire with a diameter of (4.50+B) cm is placed between the poles of the electromagnet. What is the induced EMF in the loop, if the electromagnet is turned on to full strength in (1.20+C) milliseconds? Assume the loop is perpendicular to the magnetic field. Calculate the answer in volts (V) and rounded to three significant figures.

A: 1

B: 4

C: 6
