Question:

Consider an MRI (magnetic resonance imaging) magnet that produces a magnetic field B = 1.5 T at a current I = 140 A. Assume the magnet is a solenoid with a radius of 0.30 m and a length of 2.0 m.
(a) What is the number of turns of the solenoid?
(b) What is its inductance?
(c) How much energy is stored in this magnet?
(d) If all the energy in part (b) were converted to the kinetic energy of a car (m = 1000 kg), what would the speed of the car be?
