NEET Physics Magnetic Properties of Materials MCQ Question
Which of the following statements best describes the behavior of magnetic field lines around a magnetic material?
They form closed loops without beginning or end.
They emanate from the north pole and terminate at the south pole.
They can cross each other at points where the field is weak.
They are straight lines that extend indefinitely.
Correct Answer
Detailed Explanation
Magnetic field lines form closed loops, as the net flux over any closed surface must be zero, meaning as many lines enter as leave the surface.
