Задача 31048.

The square contour and the long straight wire are in the same plane. The magnetic moment of the circuit is 0.04 A * m ^ 2. I1 = 3 A, a = b = 10 cm. The circuit is rotated 180 ° around an axis parallel to the current I1 and passing through the middle of the circuit. Determine the perfect job when turning.

A detailed solution with a brief record of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
