A rod AB of length L is placed in a cylindrical region time varying magnetic field as shown in figure-5.360 , with the rate of increasing magnetic induction C T/s. find the potential difference across ends of rod due to induced electric field in the region.

Magnetic field in cylindrical region of radius R in inward direction is as shown in figure.

Magnetic field in cylindrical region of radius R in inward direction is as shown in figure.

The potential difference across the ends of the rod moving with velocity v perpendicular magnetic field is

A cylindrical region of magnetic field is produced by an electromagnet as shown in the figure. A wint carrying a current of 0.5 A is placed perpendicularly to the axis of the cylindrical region. If the magnetic field produced by the electromagnets is 2.0 T in strength and the radius of cylindrical region is 5 cm, find the magnetic force acting on the wire due to the magnetic field in the region.

A rod of length l is rotated about its one end, perpendicular to a magnetic field of induction B What is the e.m.f induced in the rod
