Question

The main magnet in an MRI machine is a superconducting solenoid 1.8 m long and 70 cm in diameter. During normal operation, the current through the windings is 120 A and the magnetic field magnitude is 1.5 T. How many turns does the solenoid have? How much energy is stored in the magnetic field during normal operation?

Step 1

Given: Length of solenoid, L = 1.8 m Diameter of solenoid, D = 70 cm = 0.7 m Current through windings, I = 120 A We know that the number of turns in a solenoid is given by: N = (L / D) * (I / B) where B is the magnetic field magnitude. Substitute the given Show more…
