NEET Physics Magnetic Force on Current MCQ Question
Consider two long parallel conductors 'a' and 'b' carrying currents I_a and I_b, respectively, and separated by a distance d. If the magnetic field created by conductor 'a' at the location of conductor 'b' is B_a, which of the following correctly describes the direction of the force F_ba experienced by 'b' due to the field B_a?
Towards conductor 'a'.
Away from conductor 'a'.
Perpendicular to the plane containing 'a' and 'b'.
Parallel to the current in conductor 'b'.
Correct Answer
Detailed Explanation
The direction of the force F_ba on conductor 'b' due to B_a is towards conductor 'a', as per the right-hand rule and the context provided in Chunk 2.
