6 FAQs about [How do ferromagnetic materials store energy ]
What is a ferromagnetic material?
Ferromagnets are materials that become strongly magnetized in response to an applied magnetic field, even retaining some magnetization when the applied magnetic field is removed. A naturally occurring ferromagnetic material is magnetite or lodestone, Fe \ (_3\) O \ (_4\).
What happens when a magnetic field is applied to a ferromagnetic material?
Rotation of magnetic moments across a 180 \ (^\circ \) Bloch wall When a magnetic field is applied to a ferromagnetic material, work is done by the magnetic field to reorient the domain magnetization directions to a direction more closely aligned with that of the applied field. There are several processes by which this occurs.
How does a ferromagnetic material work?
Below the Curie point, atoms that behave as tiny magnets in ferromagnetic materials spontaneously align themselves. They become oriented in the same direction, so that their magnetic fields reinforce each other. One requirement of a ferromagnetic material is that its atoms or ions have permanent magnetic moments.
Why is ferromagnetism important?
The ability to generate and maintain a magnetic field without the need for a constant external source of power makes ferromagnets highly valuable. The concept of ferromagnetism stems from the alignment of magnetic moments of the atoms within the material. Magnetic moments are tiny regions of electron spins that generate a magnetic field.
Why do ferromagnetic materials have a net magnetization?
The microscopic evidence about magnetization indicates that the net magnetization of ferromagnetic materials in response to an external magnetic field may actually occur more by the growth of the domains parallel to the applied field at the expense of other domains rather than the reorientation of the domains themselves as implied in the sketch.
Why do ferromagnetic materials exhibit strong magnetic behavior?
Below the Curie temperature, these materials exhibit strong magnetic behavior. Domains: Ferromagnetic materials are composed of small regions called domains, where the magnetic moments are aligned in the same direction. The alignment of these domains determines the overall magnetization of the material.
