A generator almost always contains a coil of wire inside a magnetic field. The coil shown below has N turns and a radius of R. It is rotating in a magnetic field of strength B at an angular frequency o. This means that the angle between the area vector of the coil and the magnetic field is = wt. х a. What is the induced emf in the coil as a function of time? b. If the left side of...

Magnetic resonance imaging (MRI) is a medical technique for producing "pictures" of the interior of the body. The patient is placed within a strong magnetic field. One safety concern is what would happen to the positively and negatively charged particles in the body fluids if an equipment failure caused the magnetic field to be shut off suddenly. An induced emf could cause these particles to flow, producing an electric current within the...
