NEET Physics Magnetic Properties of Materials MCQ Question
Which of the following statements about the magnetic properties of materials is correct?
Magnetic monopoles exist and can be isolated from a magnet.
In a magnetic field, a magnetized needle aligns itself parallel to the field lines.
The magnetic potential energy is independent of the angle between the magnetic moment and the magnetic field.
When a magnet is cut in half, it results in a single magnetic pole.
Correct Answer
Detailed Explanation
A magnetized needle aligns itself parallel to the magnetic field due to the torque acting on it, which is consistent with the principles of magnetism. The other statements are incorrect based on the understanding of magnetic monopoles and potential energy.
