Motional EMF

A copper rod of length L is moving at a uniform speed v parallel to along straight wire carrying a current of I as shown in figure-5.25. The rod is perpendicular to the wire with its ends at distance a and b from if . Calculate the motional EMF induced in the rod.

Question based on Motional Electro motive force (emf)

Assertion : Motional induced emf e = Bvl can be derived from the relation e = -(dtheta)/(dt) Reason : Lenz's law is a consequence of law of conservation of energy.

A metal rod is falling toward the surface of the Earth near the equator. As it falls, one end of the rod become positively charged due to the motional emf of the rod through the Earth's magnetic field. The rod is oriented so that

A wire forming one cycle of sine curve is moved in x-y plane with velocity vec(V)=V_(x)hat(i)+V_(y)hat(j) . There exist a magnetic field vec(B)=-B_(0)hat(k) . Find the motional emf decelop across the ends PQ of wire.
