NEET Physics Magnetic Force on Current MCQ Question
Imagine a diagram showing two long parallel conductors 'a' and 'b' separated by a distance 'd', each carrying parallel currents I_a and I_b respectively. If the magnetic field B_a produced by conductor 'a' is directed downwards at conductor 'b', what is the direction of the force on conductor 'b' due to the magnetic field B_a?
Towards conductor 'a'
Away from conductor 'a'
Perpendicular to the plane of the conductors
No force is exerted on conductor 'b'
Correct Answer
Detailed Explanation
The force on a current-carrying conductor in a magnetic field is given by the right-hand rule, and the force on conductor 'b' due to B_a is towards conductor 'a'.
