average emf is it same as induced emf??
Q: a 25-turn circular coil of wire has diameter 1.00m. it is placed with its axis along the direction of the earth'smagneticfield of 50.o uT, and then in 0.200s it is flipped 180 degrees. an average emf of what magnitude is generated in the coil?
N = 25
r = .5m --------> A = 0.785m square
B = 50.0uT
t = .200s
emf = [25 * 0.785 *50 * 10^-6 * (cos180)] / .200
am i on the right track
