STANDARD Physics Magnetic Properties of Materials MCQ Question
A ball of superconducting material is dipped in liquid nitrogen and placed near a bar magnet. In which direction will it move?
Away from bar magnet
Towards the bar magnet
Around the bar magnet
Remain constant
Correct Answer
Detailed Explanation
Here, χ = -1 then μᵣ = 1 + χ ⇒ μᵣ = 1 + (-1) = 1 - 1 = 0. Since, magnetic susceptibility of given material is less than one. Hence, the given magnetic material is a diamagnetic material.
