| 11. | Both cards were demagnetized, said the manager, rounding up the usual suspects.
|
| 12. | :Permanent magnets always demagnetize, it's just a matter of time.
|
| 13. | Ferrite magnets are much more resistant to being demagnetized and are thus more robust.
|
| 14. | The new card was demagnetized as well.
|
| 15. | Magnetic media should also be kept away from magnetic sources, which could demagnetize them.
|
| 16. | A manager checked my card and found the strip that stores electronic account information was demagnetized.
|
| 17. | The current or magnetic field is then slowly reduced to zero, leaving the part demagnetized.
|
| 18. | Yet another kind of remanence can be obtained by demagnetizing the saturation remanence in an ac field.
|
| 19. | -- Cards can be stolen or demagnetized, leaving a consumer stranded without currency as a backup.
|
| 20. | Where is the magnetization of the sphere and is called the demagnetizing factor and equals for a sphere.
