Question:
An insulated copper wire of 100 turns is wrapped around a wooden cylindrical core of the cross sectional area 24 cm^2 . The two ends of the wire are connected to a resistor. The total resistance in the circuit is 12ohm. If an externally applied uniform magnetic field in the core along its axis changes from 1.5 T in one direction to 1.5 T in the opposite direction, the charge flowing through a point in the circuit during the change of magnetic field will be ____________ mC.
