Magnetic permeability is maximum for
Text Solution
Verified by ExpertsThe correct answer is:
C
Step 1: Understand the types of magnetic materials.
Among the options provided, ferromagnetic substances have the maximum magnetic permeability compared to diamagnetic and paramagnetic substances. Therefore, the correct answer is Option C: Ferromagnetic substance.
- Diamagnetic substances are materials that create an opposing magnetic field when exposed to an external magnetic field. Their magnetic permeability is slightly less than that of vacuum (μ < μ0) and they do not retain any magnetization in the absence of an external field.
- Paramagnetic substances are materials that have unpaired electrons and align with an external magnetic field, which results in a small positive permeability (μ > μ0), but they do not exhibit permanent magnetism once the field is removed.
- Ferromagnetic substances possess strong magnetic properties due to their atomic structure, allowing them to become magnetized in the presence of a magnetic field and retain that magnetization even after the external field is removed. They have the highest magnetic permeability (μ >> μ0).
Among the options provided, ferromagnetic substances have the maximum magnetic permeability compared to diamagnetic and paramagnetic substances. Therefore, the correct answer is Option C: Ferromagnetic substance.
