The magnetic field strength of 50 A / m. This field is freely rotating frame flat area of 10 cm ^ 2. The plane of the first frame coincides with the direction of the magnetic field induction. Then missed a short frame current of 1 A and frame received angular acceleration of 100 s ^ 2. Assuming conditional torque constant, find the moment of inertia of the frame.

Detailed solution with a single entry conditions, formulas and laws used in the decision, the derivation and answer.
If you have any questions about the decision to write. I'll try to help.
