Task 30980.
A small 2 cm2 frame with 200 turns and 1 Ω resistance is 1 m away from a long straight wire with alternating current I = 10 * sin100pt A. The frame and the wire are in the same plane. The magnetic field of the wire within the frame can be considered homogeneous. Find: mutual inductance of the frame and wire; The maximum value of the current in the frame; Charge that has passed in the frame when the current in the wire changes from the maximum value to zero.
A detailed solution with a brief description of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
