See lessWhat are the poles of a magnet called and how are they identified?
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.

The permeability of a magnetic material is 0.9983. Name the type of magnetic materials it represents.
The given material, with relative permeability μ r = 0.9983, is a diamagnetic material. Diamagnetic materials have relative permeability slightly less than 1, indicating their tendency to repel magnetic fields.

Do the diamagnetic substances have resultant magnetic moment in an atom in the absence of external magnetic field?
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

Which of the following substances are paramagnetic? Bi, Al, Cu, Ca, Pb and Ni
The paramagnetic substances among the listed options are Al, Cu, and Ni. These materials have unpaired electrons, which create a net magnetic moment, making them weakly attracted to magnetic fields. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-5/
