The magnetic field created by the electrons of the same pair is equal and opposite in nature. Hence, the magnetic field which is created by one electron is cancelled by the other. So the net effect of the magnetic moment is zero. These kinds of substances show diamagnetic properties and are repelled by the applied magnetic field.

According to Curie's Law, the magnetization in a paramagnetic material is directly proportional to the applied magnetic field. If the object is heated, the magnetization is viewed to be inversely proportional to the temperature. The law was discovered by the French physicist, Pierre Curie.

Ferromagnets. Only certain materials (e.g., iron, cobalt, nickel, and gadolinium) exhibit strong magnetic effects. These materials are called ferromagnetic, after the Latin word ferrum (iron). A group of materials …

Paramagnetic We can work this out by looking at the molecular orbital diagram of O_2 O_2^+ has 1 fewer electron than O_2 which is what gives it the positive charge. The electron would be removed from the pi orbital, as this is the highest in energy. Removing one electron from the pi orbital still leaves one unpaired electron in the other …

The magnetic susceptibility of diamagnetic materials will be small and negative, i.e., $-1le chi le 0$ Paramagnetic Materials. The paramagnetic materials get weakly magnetised if placed in an external magnetic field. In other words, they will try to move from points exhibiting weak magnetic strength to points exhibiting a relatively stronger ...

Paramagnetic materials have some unpaired electrons, and due to these unpaired electrons, the net magnetic moment of all electrons in an atom is not added up to zero. Hence, an atomic dipole exists in this case. On …

Paramagnetic compounds contain one or more unpaired electrons and are attracted to the poles of a magnet. Elemental iron and iron (III) are paramagnetic because of the necessity of unpaired electrons in their orbitals. Iron (II) is also in this same position most of the time.

The strength of paramagnetism is proportional to the strength of the applied magnetic field. Paramagnetism occurs because electron orbits form current loops that produce a magnetic field and contribute a magnetic moment. In paramagnetic materials, the magnetic moments of the electrons don't completely cancel each other out.
