- A 1.0 m long metallic rod is rotated with an angular frequency of 400 rad s1 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 .5 T parallel to the axis exists everywhere. Calculate the emf developed between the centre and the ring.The component of the external magnetic field along the central axis of a 50 turn coil of radius 40.0 cm decreases from 2.90 T to 0.550 T in 3.00 s.
