Causes of Ferromagnetism
Ferromagnetism happens when tiny magnets in materials line up together. This alignment makes the material act like a magnet. The main causes are the arrangement of atoms and the way their magnetic moments work together. When these moments align in the same direction, the material becomes strongly magnetic. This alignment is usually influenced by factors like temperature and the material’s structure.
Curie Temperature
- Ferromagnetic materials exhibit a special temperature known as the Curie temperature. Below this temperature, these materials tend to be ferromagnetic, meaning they easily form magnets. Above the Curie temperature, their magnetic properties weaken, and they may lose their magnetism.
Magnetic Domains and Orientation
- Inside ferromagnetic materials, there are small regions called magnetic domains. Each domain has its magnetic moments (tiny atomic magnets) aligned in a particular direction. In an unmagnetized state, these domains point in random directions, canceling out each other’s magnetic effects.
- When an external magnetic field is applied, the domains start aligning in the direction of the field. As the alignment grows, the material becomes magnetized. Even after removing the external field, the magnetic domains tend to stay aligned, making the material act like a permanent magnet.
Ferromagnetic Materials
Ferromagnetic Materials are known for their magnetic property like iron and cobalt, can become strong magnets and retain their magnetic properties, finding applications in electronics for data storage and in industrial settings for devices like transformers and magnetic separators.
