Field and Wave Electromagnetics 2nd Edition by David Cheng

Exercise 59

Refer to Problem and Figure. Find the force on the circular loop that is exerted by the magnetic field due to an upward current I 1 in the long straight wire. The circular loop carries a current 1 2 in the counter clockwise direction.
Problem:
Determine the mutual inductance between a very long, straight wire and a conducting circular loop, as shown in Figure.
