Solution to task 463 from Chertov´s for extramural stud

463. A straight magnet was inserted into a wire ring connected to a ballistic galvanometer. In this case, a charge of Q = 50 μC passed through the circuit. Determine the change in magnetic flux ΔF through the ring if the resistance of the galvanometer circuit is R = 10 Ohm.
