A 1.0 m long metallic rod is rotated with an angular velocity of 400 rad. `s^(-1)` about an axis normal to the rod passing through its one end. The other end of the rod is in contact with a circular metallic ring. A constant and uniform magnetic field of 0.5 T parallel to the axis exists everywhere. Calculate the emf developed between the centre and the ring.

Explanation

`e=(Blv)/(2)=(0.5xx1xx1xx400)/(2)=100V`
