The disc rotates about an axis perpendicular to its planes and passing through its centre with an angular velocity omega . As a result of this rotation a magnetic field of induction B is obtained at the centre of the disc if we keep both the amount of charge placed on the disk and its angular velocity to be constant and varying the radius of the disc then the variation of the magnetic induction at the centre of the disc will be represented by the figure.

    A charge Q is uniformly distributed over the surface of nonconducting disc of the radius R. The disc rotates about an axis perpendicular to its planes and passing through its centre with an angular velocity 0. As a result of this rotation a magnetic field of induction B is obtained at the centre of the disc if we keep both the amount of charge placed on the disk and its angular velocity to be constant and varying the radius of the disc then the variation of the magnetic induction at the centre of the disc will be represented by the figure.
