this one' a short question from HCV--------consider 2 parallel long wires carrying current in the same direction---and placed at some distance on a perfectly smooth floor---due to mutual attraction they start moving towards each other---intially v=0 and suddenly they have non--zero kinetic energy-since magnetic forces do no work --------where's this k.e coming from ?
