The figure shows a uniform 1.50 T magnetic field that is perpendicular to the plane of a conducting, circular loop with a radius of 0.240 m. The magnetic field is downward as shown.
A) What is the magnitude of the average induced emf in the loop if the magnitude of the magnetic field is doubled in 0.100 seconds?
B) if the magnetic field is held constant at 1.50 T and the loop is rooted along a vertical axis so that is turns 30 degrees in 0.200 seconds, what is the magnitude of the average induced emf in the loop?
