Question

What type of magnetism is shown in the following alignment of magnetic moments?

Answer 1

Hint: A property of a substance produced by the motion of the electric charge and results in attractive and repulsive forces between objects. It can be observed in the diagram that the magnetic moments of all the atoms are aligned in the same direction.

Complete answer:
When the magnetic moments are aligned along the same direction i.e. along the direction of the applied magnetic field, the magnet is said to me ferromagnetic and the type of magnetism is known as ferromagnetism. In the diagram, it is shown that the magnetic moments of all the atoms are aligned in the same direction. Thus, the type of magnetism is ferromagnetism.

Ferromagnetism is exhibited by metals like iron, cobalt, etc. Ferromagnetism is a phenomenon where materials like iron, cobalt, etc. attain permanent magnetism. It is a process in which the electrically uncharged materials attract each other strongly.

Additional Information: Properties of ferromagnetic materials are as follows:
i) Atoms of ferromagnetic material have permanent dipole moments.
ii) The atomic dipoles of ferromagnetic materials are aligned in the same direction as that of the applied magnetic field.3.
iii) The intensity of magnetism is very high.
iv) Ferromagnetic substances are strongly attracted by the magnetic field
v) The ferromagnetic property of a material is lost at higher temperatures.

Note:Other types of magnetism are
a) Diamagnetism: The diamagnetic materials oppose the magnetic field and thus, get repelled by the magnetic field.
b) Paramagnetism: The magnetism due to the presence of unpaired electrons is known as paramagnetism. The magnetic moments of paramagnetic materials align themselves in the direction of the applied magnetic field.
