De Magneet van het ferriet
|
|
|
| De Magneet van het ferriet : De magneten van het ferriet worden gemaakt hoofdzakelijk van ijzer en borium met een kleine hoeveelheid strontium. Als al keramiek, zijn zij vrij bros en gemakkelijk onderbreking indien gelaten vallen op een harde oppervlakte. Zij zijn het meest economisch voor hun sterkte. De magneten van het ferriet kunnen zowel anisotroop als isotroop zijn. De anisotrope rangen zijn georiënteerd in de productierichting en moeten in de richting van richtlijn worden gemagnetiseerd. De isotrope rangen zijn niet georiënteerd en kunnen in om het even welke richting worden gemagnetiseerd Deze klasse van magneet is zeer hard, bros en bezit lagere energiekenmerken in vergelijking met andere magnetische materialen. Nochtans, is het zeer populair en wijd gebruikt wegens zijn uitstekende weerstand tegen demagnetizaion, corrosie, en de voordelige tarifering.
