Two parallel wires carrying currents in the same direction attract each other because of
Text Solution
Verified by ExpertsThe correct answer is:
D
As shown in the figure, let the conductor Y carry current i2,
situated in a magnetic field 
perpendicular to its length. t therefore, experiences a magnetic force, the magnitude of the force acting on a length l of Y is
F = i 2 Bl = = i 2 
From Fleming's left hand rule the direction of this force is towards X. Similarly, force per unit length of X due to Y is directed opposite to Y.
Hence, the conductors attract each other.
