Задача 30404.

In a uniform magnetic field with an induction of 125.6 mT, the rod rotates with a constant frequency of 10 s ^ -1 so that the plane of its rotation is perpendicular to the induction lines, and the axis of rotation passes through one of its ends. The potential difference induced at the ends of the rod is 0.1 μV. Determine the length of the bar.

Detailed solution with a short recording of the conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
