Problem: A large MRI magnet is a large solenoid (with superconducting wires having zero resistance) with diameter 0.60 m and length 1.8 m. During normal operation, the current through the windings is 110 A and the magnetic field magnitude is 1.3 T. How many total windings does the MRI magnet have? (1) 16,900 (2) 9,400 (3) 13,000 (4) 15,500 (5) 14,700

🤓 Based on our data, we think this question is relevant for Professor Weatherford's class at UF.
