| 21. | As the external field surpasses the hard material's coercivity, the hard magnet gets fully demagnetized.
|
| 22. | The demagnetizing energy is balanced by the energy of the exchange interaction, which tends to keep spins aligned.
|
| 23. | :: : : : But is an unlatched / unlocked / demagnetized door truly closed, or just parallel?
|
| 24. | Ferromagnetic materials can be divided into magnetically " soft " materials like microcrystalline structure, making them very hard to demagnetize.
|
| 25. | When an external magnetic field is applied to a demagnetize it requires heat or a magnetic field in the opposite direction.
|
| 26. | SmCo 5 magnets have a very high coercivity ( coercive force ); that is, they are not easily demagnetized.
|
| 27. | If the motor of the vacuum is powerful enough, it can demagnetize the tape and the recording will be compromised.
|
| 28. | The demagnetizing field of an arbitrarily shaped object is very difficult to calculate even for the simple case of uniform magnetization.
|
| 29. | As size of a ferromagnet increases, the single-domain state incurs an increasing energy cost because of the demagnetizing field.
|
| 30. | There is a critical size at which the balance tips in favor of the demagnetizing field and the multidomain state is favored.
