Question

Consider two straight parallel conductors $A$ and $B$ separated by a distance $x$ and carrying individual currents $I_A$ and $I_B$ respectively. If the two conductors attract each other, it indicates that

• A. the two currents are parallel in direction
• B. the two currents are anti-parallel in direction
• C. the magnetic lines of induction are parallel
• D. the magnetic lines of induction are parallel to length of conductors

Answer 1

Answer: (A)

The two conductors are attracting each other, which means that currents flowing are parallel indirection.
