1.	A rod of length `l` is rotating with an angular speed `omega` about one of its ends which is at a distance a from an infinitely long wire carrying current `i`. Find the emf induced in the rod at the instant shown in .
Answer» `E=int(mu_(0)i)/(2pi(a+rcos theta))xx(romega)*(dr)` `E=(mu_(0)omegai)/(2pi) int_(0)^(l)( r)/(a+r cos theta) drimplies E=(mu_(0)I omega)/(2pi cos theta)[l-(a)/(cos theta)ln""((a+l cos theta)/(a))]`
