Задача 30421.

A round frame with 200 turns and an area of 100 cm ^ 2, rotates uniformly in a uniform magnetic field about an axis perpendicular to the field and coinciding with its diameter. Calculate the rotation frequency for field induction of 0.03 T if the maximum current that is induced in the frame with its resistance of 20 Ohm is 0.02 A.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
