Find the current

It is given PQ is a wire of negligible resistance which travel smoothly over two conduction parallel wire X and Y separated by distance d and θ is the fixed angle made by PQ and B is the strength of the magnetic field perpendicular to the plane of the paper and outward

hence motion electric field = vB

the direction of this electric field is along CD perpendicular to

EMF of the induced in wire PQ

e = length of PQ * motional electric field QP

current in the wire
