Question

Which of the following properties shows the property of ferromagnetic substances?
A. The ferromagnetic property depends on temperature.
B. The ferromagnetic property does not depend on temperature.
C. At high enough temperature ferromagnet becomes a diamagnet
D. At low temperature ferromagnet becomes a paramagnet

Answer 1

Hint: The above problem can be resolved using the concepts and applications of the nature of materials. Ferromagnetism depends on the domain of the material. The domain means the orientation of the atoms in the substances and the electrons' orientation to respond to the magnitude of the external magnetic field. Moreover, the ferromagnetic materials have vigorous numbers of magnetic substances like iron, cobalt, and many more.

Complete step by step solution:
The ferromagnetic substances are those substances that are made by the compositions of the magnetized materials like iron, cobalt, and nickel. Moreover, these materials' composition is present even at such a higher concentration than these substances respond very strongly to the magnetic field.
In addition, the temperature of the ferromagnetic material depends on the hypothetical value of temperature, known as the curie temperature. And at the temperature below that of the Curie temperature, the material is known as a ferromagnet. If the condition is reversed, that is the substance's temperature being greater than that of the curie temperature. Then, in this case, the material is known as paramagnet.

Therefore, the ferromagnetic property depends on temperature, and option (A) is correct.

Note: Try to understand the meaning of ferromagnetism and the concept related to ferromagnetism. Ferromagnetism depends on magnetic substances like iron and nickel. More will be the composition of these materials; the property of ferromagnetism is enhanced more significantly. Moreover, there are several applications of ferromagnetic substances like that in the manufacturing industry and many more.
