What happens to the effective inductance when a ferromagnetic core is ...
Introduction:
When a ferromagnetic core is introduced in an inductor, it significantly affects the effective inductance of the inductor.
Explanation:
- Increases: The effective inductance of an inductor increases when a ferromagnetic core is introduced. This is because the presence of the ferromagnetic core increases the magnetic flux density within the core material, resulting in a higher inductance value.
- Explanation:
- The ferromagnetic core enhances the magnetic field generated by the current flowing through the inductor, leading to a higher inductance value.
- The increased magnetic flux density within the core material results in a stronger magnetic field, which in turn increases the inductance of the inductor.
- This increase in inductance is a result of the core material effectively concentrating the magnetic field lines, leading to a higher inductance value compared to an air core inductor.
Therefore, when a ferromagnetic core is introduced in an inductor, the effective inductance increases due to the core material's ability to enhance the magnetic field and concentrate the magnetic flux lines, resulting in a stronger inductance value.
