The resistivity of a certain metal is p, using a wire drawing machine, a wire of uniform cross section is made out of volume V of the metal. The wire is shaped in a square loop, which is placed in a uniform magnetic field B whose direction is parallel to the axis of the loop. Find the charge flown through any crosssection of the wire, when the magnetic field is switched off.
