NEET Physics Magnetic Properties of Materials MCQ Question
What happens to the individual atomic dipole moments of a paramagnetic material when placed in a strong external magnetic field?
They align in the same direction as the external field.
They become completely randomized.
They repel each other.
They cancel each other out.
Correct Answer
Detailed Explanation
In a strong external magnetic field, the individual atomic dipole moments of a paramagnetic material can align and point in the same direction as the external field, leading to a net magnetisation, especially at low temperatures.
