I have a 250- turn circular coil of wire, 0.10 m in diameter, perpendicular to a 0.050 T magnetic field as shown below. I flip the coil 180 degrees in 1/30 of a second. What is the average voltage created across the ends of the coil?

A. -6.0 V
B. -12 V
C -3.0 V
D. -24 V

    I think we might be in the same physics class. For this question I put -12 and was incorrect...what did you put so we can get the answer choices down to two options?

    i put -6.0 V. i think that's it
