In your new engineering job, you are requested to design a loop which will provide a maximum magnetic field of 50mT (milliTesla) at the center of the loop. The design specifications are that it must have a radius of 30 cm, and that it have a maximum current current of 130 A. Q) Given these specifications, determine the minimum number of turns that will produce a a 50 mT field at its center given the above specifications

Expert Solution
Concept
The magnetic field at the center of the circular loop is given by
Where N = number of turns of the loop, I = Current in the loop, R = Radius of the loop,
= Magnetic permeability of free space = 4π × 10- 7 T.m.A- 1
