Ferrites are Ferromagnetic materials.

- Ferrites are a type of magnetic material that are characterized by their strong magnetic properties. They are made up of a combination of iron oxide (Fe2O3) and other metallic elements, such as nickel, zinc, or manganese.
- Ferrites are known for their high magnetic permeability, which means they can easily establish and maintain a magnetic field when exposed to an external magnetic field.
- They are also highly resistant to demagnetization, which makes them useful in applications where a stable magnetic field is required.
- Ferrites have a crystalline structure, which allows for the alignment of their magnetic domains. This alignment results in the material having a permanent magnetization even after the external magnetic field is removed.
- The ferromagnetic nature of ferrites allows them to exhibit properties such as hysteresis, where the magnetization of the material lags behind the applied magnetic field. This property is used in the design of magnetic cores for transformers and inductors, where the hysteresis loop helps to reduce energy losses.
- Ferrites also have high electrical resistivity, which makes them suitable for applications in which electrical conductivity is not desired. They are commonly used in electronics and telecommunications for their magnetic and electrical properties.
- Unlike paramagnetic materials, which are weakly attracted to an external magnetic field, and diamagnetic materials, which are weakly repelled by an external magnetic field, ferrites exhibit strong attraction to magnetic fields due to their ferromagnetic nature.
- Therefore, the correct answer is option 'C' - Ferrites are Ferromagnetic materials.
