Question

Which of the following substances are strongly attracted by magnetic fields?

• A. Ferromagnetic Material
• B. Diamagnetic Material
• C. Paramagnetic
• D. None of the above

Answer 1

The correct option is A

Ferromagnetic Material

The explanation for the correct option:

In the case of option A,

Ferromagnetic Material:

1. Ferromagnetic materials have spontaneous net magnetization at the atomic level even in the absence of an external magnetic field.
2. When ferromagnetic materials are exposed to an external magnetic field, they become strongly magnetized in the direction of the field.

The explanation for incorrect options:

In the case of option B,

Diamagnetic Material:

1. Diamagnetic materials are those that magnetize freely when placed in a magnetic field.
2. The magnetization is oriented in the opposite direction as the magnetic field.

In the case of option C,

Paramagnetic Material:

1. These are metals that have a weak magnetic attraction. Aluminum, gold, and copper are among them.
2. Permanent dipole moments or permanent magnetic moments exist in paramagnetic materials.

Hence, Option(A) is correct.
