Question:
A conducting disc 20cm in diameter pivoted by a vertical spindle which is lying in the uniform vertical magnetic field of flux density 0.3 T. A fixed brush is connected at the edge of the disc. When a 4-ohm resistance is connected across the brush and the spindle, a current of 15mA was observed to flow the resistor. Determine the velocity at which the disc is rotating.
