The long straight wire in the figure carries a current I that is decreasing with time at a constant rate. The circular loops A, B, and C all lie in a plane containing the wire. The induced emf in each of the loops A, B, and C is such that A B A) no emf is induced in any of the loops. B) a counterclockwise emf is induced in all the loops. C) a clockwise emf is induced in all the loops. D) loop A has a counter-clockwise emf, loops B and C have clockwise emfs. E) loop A has a clockwise emf, loop B has no induced emf, and loop C has a counterclockwise emf. F) loop A has a counter-clockwise emf, loop B has no induced emf, and loop C has a clockwise emf.
