Magnetic field lines around a solenoid
Web12 sep. 2024 · When a patient undergoes a magnetic resonance imaging (MRI) scan, the person lies down on a table that is moved into the center of a large solenoid that can generate very large magnetic fields. The solenoid is capable of these high fields from high currents flowing through superconducting wires. WebA 0.100-m long solenoid has a radius of 0.050 m and 1.50 x 104 turns. The current in the solenoid changes at a rate of 6.0 A/s. A conducting loop of radius 0.0200 m is placed at the center of the solenoid with its axis the same as that of the solenoid as shown. 1. Determine the induced emf in the loop. EMF=µ 0 (dI/dt)(N/L)πr l 2 A) 0.7 x 10-3 V
