Question

3 Explain the following with suitable examples:
(1) Ferromagnetism
(11) Paramagnetism
(iii) Ferrimagnetism
(iv) Antiferromagnetism
(v) 12-16 and 13-15 group compounds.​

Answer 1

✎The magnetic domains that cause ferromagnetism are regions in which the spins of large numbers of unpaired electrons of neighboring atoms align with each other, creating a unidirectional magnetic field

✎Paramagnetic materials, such as aluminum and platinum, become slightly magnetized when exposed to a magnetic field, but they lose their magnetism when the field is removed.

✎ferrimagnetic material point in the same direction and some in the opposite direction.

✎antiferromagnetism, the magnetic moments of atoms or molecules, usually related to the spins of electrons, align in a regular pattern with neighboring spins
