A diamagnetic material in a magnetic field moves (a) from stronger to the weaker parts of the field (b) from weaker to the stronger parts of the field (c) perpendicular to the field (d) in none of the above directions

Answer: (a). Induced moment is opposite to the field, so the energy -m is lower where B is weaker. So the material moves from stronger to weaker parts of the field. So the answer is (a).

A diamagnetic material in a magnetic field moves

Show answer and solution

Answer: (a)

Induced moment is opposite to the field, so the energy $-\vec{m}\cdot\vec{B}$ is lower where $B$ is weaker.
So the material moves from stronger to weaker parts of the field.
So the answer is (a).
