plz explain that in part C) if  the wire is placed along its length then a potential difference will exist between the ends of the wire ( bcoz, wire will be of finite length and so apply V=Ed)  so can't current flow inside wire, and then thermal energy be also developed, also if charge are induced, why will they stay at the ends of the wire?? (rates assured) jee-2007 question (paper1) developed

 CHARGES WONT BE INDUCED BUT WILL BE TRANSEFEERD FROM ONE PART TO ANOTHER IN SUCH A MANNER THAT THE NET FIELD PRODUCED DUE TO TRANSFER OF CHARGES EXACTLY OPPOSED THE RESULTANT ELECTRIC FIELD. AND THE CIRUIT ISNT COMPLEATE FOR CURRENT TO FLOW THEN HOW WILL CURRENT FLOW SO NO THERMAL ENERGY ALSO.

ITS LIKE THIS U KNOW THE INDUCED EMF IN A ROD MOVING IN A UNIFORM MAGNATIC FIELD? WHERE A POTENTIAL DIFFERENCE IS CREATED ACROSS THE WIRE? SOMETHING LIKE THAT
