A conducting rod of length L with one end pivoted is rotated with uniform angular speed W in a vertical plane normal to the magnetic field B.Deduce an expression for emf induced in this rod.?plz answer this question as soon as possible and if possible plz answer the question today only..plz plz plz...
As given E=rate of change of magnetic flux.
(Here Time T will be the time taken by the rod,because in this time,emf rises from peak to zero)
Also W=2(pi)/T,so T=2(pi)/W
(I am sorry that it has become complicated because the subscripts are not working on my computer).
