Unformatted text preview: perpendicular to the same changing magnetic field. The voltage induced in each of the coils is the same. What is the radius of the circular coil? E = -Nd/dt and = BA where B is the field and A is the area. All other things being the same, therefore the circular loop with twice the number of turns must have half the area. A = 0.018 = . R 2 or R = 7.6 cm....
