Question: A single conducting wire is shaped into a circular loop with a diameter of 9.0 cm. At first, the wire is oriented so that its plane is perpendicular to a magnetic field of 0.50 T pointing straight up. In a time period of 0.30 s, the field is changed to one of 0.25 T pointing straight down.
Part A: What is the average induced emf in the coil in mV?
I need tutor help to solve the above question, thanks in advance.
