The magnetic field produced by the solenoid in a magnetic resonance imaging (MRI

Question

The magnetic field produced by the solenoid in a magnetic resonance imaging (MRI) system designed for measurements on whole human bodies has a field strength of 6.0 T, and the current in the solenoid is 2.5 x 10^2 A. What is the number of turns per meter of length of the solenoid? Note that the solenoid used to produce the magnetic field in this type of system has a length that is not very long compared to its diameter. Because of this and other design considerations, your answer will be only an approximation.

Explanation / Answer

For a solenoid... . mag field = ? * turns permeter * current or . 6.0 = 4? x10-7 * turns per meter * 150 . turns per meter = 31830
