4927 turn solenoid is carrying a current of 11.1 A. The solenoid is 67.3 cm long. What is the magnitude of the magnetic field (in milli-tesla) through the center of the solenoid?

The superconducting magnet of an MRI scanner requires 810 A of current to create a magnetic field of 4.5 T in the center of its solenoid coil with a 0.65 m radius.    If the solenoid is 1.9 m long, how many loops of wire does it have?  N =

. A cylindrical solenoid has a length of 10 cm and a radius of 1 cm. It is tightly wound with 100 turns of wire. The axis of the solenoid is aligned with the z-axis, and the center of the solenoid is at the origin. The current flowing through the solenoid is 1.5 A. What is the magnetic field at the following points of interest? B, Tesla Point of interest x=0, y=0, z=2 cm x=0, y=0, z=200 cm x=0, y=2 cm, z=0 cm سا

You make a solenoid with 500 turns of wire. The solenoid has a radius of 1.5 cm.  You then curve this solenoid into a circle with a radius of 8.5 cm, and run a current of 3.0 Amps through the resulting toroid.  What is the magnetic field inside the tube of the toroid?
