Task 30132.
A wire loop with an area of 500 cm ^ 2 and a resistance of R = 0.1 Ohm rotates uniformly in a uniform magnetic field (B = 0.5 T). The axis of rotation lies in the plane of the ring and is perpendicular to the lines of magnetic induction. Determine the maximum power Pmax required to rotate the circuit with an angular speed of 50 rad / s.
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.
If you have questions about the solution, write. I try to help.
