Question

Which of the following substances are strongly attracted by magnetic fields?
A. Ferromagnetic Material.
B. Diamagnetic Material.
C. Paramagnetic Material.
D. None of the above.

Answer 1

Hint: To solve this question we should know about:
Magnetic material: Magnetic materials are materials that have magnetic properties and are studied and used for that reason. The magnetic dipole moment associated with the inherent angular momentum, or spin, of a material's electrons determines much of its magnetic response.
So, we first read about the properties of each type of material then we can decide on it.

Complete step by step solution:
Ferromagnetic Material: Ferromagnetic substances are those that become significantly magnetized when exposed to an external magnetic field. They also have a tendency to travel from a weak to a high magnetic field and become powerfully attracted to a magnet. Individual atoms in a ferromagnetic substance, like those in a paramagnetic material, have a dipole moment.
Diamagnetic material: Diamagnetism is the tendency of diamagnetic substances to shift from the stronger to the weaker parts of the external magnetic field. A magnet repels diamagnetic material, which is another way of putting it.
Paramagnetic Material: The term "paramagnetic" refers to materials that become weakly magnetized in the presence of an external magnetic field. These compounds tend to change from a weak to a strong magnetic field when exposed to an external magnetic field. In other words, these materials are prone to being weakly attracted to a permanent magnet. Individual atoms in a paramagnetic material have a dipole moment, which interact with one another and spontaneously align in the same direction when placed in a magnetic field, resulting in magnetization. The magnetism of a paramagnetic substance is inversely proportional to the absolute temperature until it achieves saturation, according to Curie's law.
Hence, the magnetic field attracts ferromagnetic materials significantly.
So, the correct option is A.

Note:
Magnetic fields mediate a class of physical properties known as magnetism. A magnetic field is created by electric currents and the magnetic moments of elementary particles, which operates on other currents and magnetic moments. Electromagnetism is a multifaceted phenomenon that includes magnetism. The most well-known effects occur in ferromagnetic materials, which are highly attracted to magnetic fields and can be magnetized to become permanent magnets that generate magnetic fields. It is also feasible to demagnetize a magnet. Iron, cobalt, and nickel, as well as their alloys, are the most prevalent ferromagnetic materials.
