How does the magnetic compass needle behave in a magnetic field ?
Correct answer: C. It assures a position which follows a line of magnetic flux
- A. It assures a position right angle to magnetic field
- B. It starts rotating
- C. It assures a position which follows a line of magnetic flux
- D. None of the above
Explanation
A compass needle is itself a small magnet, so its north pole aligns with the local magnetic field direction. It settles tangentially along a magnetic flux line rather than at right angles to it.
