Task 30606.
Round frame having N = 200 turns and the area S = 100 cm ^ 2 uniformly rotating in a uniform magnetic field around an axis perpendicular to the field and passing through the diameter of the frame. Calculate the speed at an induction field B = 0,03 T, if the maximum current induced in the frame when the resistance R = 20 ohms, is Im = 0,02 A.
Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
