1.	In an experiment , setup A consists of two parallel wires which carry currents in opposite directions as shown in the figure. A second setup B is identical to setup A, except that there is a metal plate between the wires Let FA and FB be the magnitude of the force between the two wires in setup A and setup B, respectively(A) FA > FB ≠ 0 (B) FA < FB (C) FA = FB ≠ 0 (D) FA > FB = 0
Answer» Correct Option :- (C) F_A = F_B ≠ 0 Explanation :- In setup B, A metal is placed, due to which metal may get magnetized and it may also exert force on current carrying wire but force between two wire remain same however net force on wire may get charge due to magnetic field produced by magnetized metal.

Answer»

Correct Option :- (C) F_A = F_B ≠ 0

Explanation :-

In setup B, A metal is placed, due to which metal may get magnetized and it may also exert force on current carrying wire but force between two wire remain same however net force on wire may get charge due to magnetic field produced by magnetized metal.
