The magnetic field of a proton is relatively close to that of a circular current loop 0.650 times 10^-15 m in radius carrying 1.05 times 10^4 A. An MRI machine is required to be able to manipulate these fields. To see why an MRI utilizes iron to increase the magnetic field generated by a coil, calculate the current needed in a 400 loop-per-meter circular coil 0.660 m in radius to generate a 1.20 T field (typical of an MRI instrument)...
To see why an MRI utilizes iron to increase the magnetic field created by a coil, calculate the current needed in a 460–loop–per–meter circular coil 0.600 m in radius to create a 1.40–T field (typical of an MRI instrument) at its center with no iron present.

Please solve: 1. A long, current-carrying solenoid with an air core has 2200 turns per meter of length and a radius of 0.0230 m. A coil of 180 turns is wrapped tightly around the outside of the solenoid, so it has virtually the same radius as the solenoid. What is the mutual inductance of this system?
