A magnet has two poles: the North-seeking pole (or North pole) and the South-seeking pole (or South pole). These poles align with Earth's magnetic field, with the North-seeking pole pointing towards Earth's geographic North, and the South-seeking pole pointing towards geographic South.

Diamagnetic materials have relative permeability slightly less than 1, indicating their tendency to repel magnetic fields.
No, diamagnetic substances do not have a resultant magnetic moment in an atom in the absence of an external magnetic field. This is because their electron pairs have opposite spins, which cancel each other out, resulting in no net magnetic moment. For more visit here: https://www.tiwariacademy.com/nRead more

Two characteristic properties distinguishing paramagnetic and diamagnetic materials are:
(i) Diamagnetic substances move from stronger to weaker regions of a non-uniform magnetic field, whereas paramagnetic substances move from weaker to stronger regions.
