| 41. | Ferrite magnets are much more resistant to being demagnetized and are thus more robust.
|
| 42. | A ferrite choke was added to prevent RF signals and lightning from triggering the mine.
|
| 43. | Vector magnetometers are subject to temperature drift and the dimensional instability of the ferrite cores.
|
| 44. | Sometimes a ferrite core is present also.
|
| 45. | Batteries require " electrolytic manganese dioxide " while ferrites require " chemical manganese dioxide ".
|
| 46. | Baluns can be made using ferrite toroid cores or even from the coax feedline itself.
|
| 47. | This loss heats the ferrite, but normally it is a negligible amount of heat.
|
| 48. | Surface-mount ferrite beads are available.
|
| 49. | Correlated magnetic structures can be developed from ferrites, rare-earth materials ( ex.
|
| 50. | The usual magnetostrictive materials used for the transducer are either ferrite or compressed powdered iron.
