If a diamagnetic substance is brought north and south poles of a bar magnet, it is repelled by both poles.
Diamagnetic substances are materials that create an induced magnetic field in the opposite direction of the applied magnetic field, causing them to be repelled by a magnet. This is because diamagnetism results from the formation of opposing magnetic fields when placed in a magnetic field, causing the substance to be pushed away.
