Consider an electromagnet, shown by the field lines in the attached figure, capable of
producing a maximum magnetic field of (1.50 + A) T (teslas). A circular loop with N = (D + 15)
turns of wire with a diameter of D = (4.50 + B)cm (centimeters) 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)ms (milliseconds)? Assume the loop is perpendicular to the magnetic
field. Calculate the answer in volts (V) and rounded to two significant figures.
