NEET Physics Magnetic Force on Current MCQ Question
A diagram depicts a current-carrying circular loop with a magnetic field dB due to a line element dl. The components of dB are shown along and perpendicular to the loop's axis. Which component of dB remains after considering the entire loop?
The x-component
The y-component
The z-component
The perpendicular component
Correct Answer
Detailed Explanation
The perpendicular components of the magnetic field dB due to the current-carrying circular loop cancel out due to symmetry, leaving only the x-component as the net contribution.
