| 11. | Ferromagnetic materials owe their properties to an enormous number of embedded tiny magnets, called domains.
|
| 12. | A familiar example of SSB is in ferromagnetic materials.
|
| 13. | Think about a permanent magnet and a chunk of ferromagnetic material ( like iron ).
|
| 14. | Computing the magnetic field and force exerted by ferromagnetic materials is difficult for two reasons.
|
| 15. | But in a ferromagnetic material, all the atomic moments are aligned even without an external field.
|
| 16. | A modern HDD records data by magnetizing a thin film of ferromagnetic material on a disk.
|
| 17. | It turned out, for example, that small clusters of a ferromagnetic material are super-paramagnetic rather than ferromagnetic.
|
| 18. | Even an iron ( " soft " ferromagnetic material ) nail can retain a bit of the magnetization.
|
| 19. | The magnetic moments of atoms in a ferromagnetic material cause them to behave something like tiny permanent magnets.
|
| 20. | This can result in ferromagnetic materials having no spontaneous magnetism as domains could potentially balance each other out.
