Box containing 10 turns of an area of 5 cm2, each attached to a ballistic galvanometer with an internal resistance of 58 ohms and a ballistic constant 1 x 10 -6 C / mm. Resist frames 2 ohms. The frame is placed in the coil so that the magnetic field lines are perpendicular to the plane of the frame. Determine the value of magnetic induction in the solenoid switch if the current in the coil is reversed in the circuit of the galvanometer 30, the amount of electricity flowing SCLC. How many millimeters deviate bunny on the scale of the galvanometer?

Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
