Question

If a diamagnetic substance is brought near either pole of a bar magnet, how does it behave?

G1 Physics · Accepted Answer

Step 1: A diamagnet acquires a weak induced moment opposite to the external magnetic field. Step 2: A nonuniform magnetic field is stronger close to either pole of a bar magnet; the diamagnet moves toward smaller field strength. Step 3: Thus it is repelled from both the north pole and the south pole. Final A. Final answer: (A) repelled by both the poles.
