Magnetism + Sequence = Maquence
The radii of the successive half rings are as follows: \[R, 3R^2,5R^3,7R^4 \ldots \infty\]
Now if we rotate the Rod about the point \(O\) with constant angular velocity \(\omega \), find the magnitude of the induced emf developed in the rod.
- The rod is very thin.
- The rod is rigid.
- \(B _0=2.0\) Tesla
- \(\omega =5\) rad/sec
- \(R=0.5\) m
