A small coil is introduced between the poles of an electromagnet so that its axis coincides with the magnetic field direction. The number of turns is `n` and the cross sectional area of the coil is `A`. When the coil turns through `180^(@)` about its diameter, the charge flowing through the coil is `Q`. the total resistance of the circuit is `R`. what is the magnitude of the magnetic induction?

A small coil is introduced between the poles of an electromagnet so that its axis coincides with the magnetic field direction. The cross-sectional area of the coil is equal to S = 3.0 mm^2 , the number of turns is N = 60 . When the coil turns through 180^@ about its diameter, a galvanometer connected to the coil indicates a charge q = 4.5muC flowing through it. Find the magnetic induction magnitude between the poles, provided the total resistance of the electric circuit equals R = 40 Omega .
