A rod of mass `m`, length `l` and resistance `R` is sliding down on a smooth inclined parallel rails with a cinstant velocity `v`. If a uniform horizontal magnetic field `B` exists, then find thevalue of `B`.

A glass rod of length l moves with velocity v in a uniform magnetic field B. What is the e.m.f induced in the rod?

A glass rod of length l moves with velocity v in a uniform magnetic field B. What is the e.m.f induced in the rod?

A conducting rod ab of length l, mass m and resistance R slides on a smooth, thick pair of metallic rails. The plane of the rails makes an angles theta with the horizontal. A magnetic field B acts along the perpendicular to the horizontal plane in upward direction. If the rod slides down on the rails at a constant speed v, then show that B=sqrt((mgRsintheta)/(l^(2)vcos^(2)theta)) .
