For natural magnets to be formed, magnetite (ore of iron) must have traces of maghemite. These natural magnets are not as strong as artificial magnets made with desired strengths and shapes.

Magnetised Ferrite is a resource. Magnetised Ferrite (Fe++) is a resource and one of the metal elements. The British spelling of this word is used in the wiki. Highly processed metal, requiring several stages of processing in a Refiner. Used in the creation of advanced structures and technologies. Avoid ingestion. From resource cans dropped by defeated …

Pyrrhotite is the second most common magnetic mineral. It can easily be identified by its magnetic properties, lower hardness, and bronze color. Lodestone: A specimen of lodestone that has attracted numerous tiny particles of iron. This specimen is approximately 10 centimeters across. Magnetite Crystals: Octahedral crystals are a common crystal ...
Une pierre d'aimant était un appareil de navigation fabriqué à partir d'un bout de magnétite naturellement magnétisé. ... de comment la magnétite devient magnétisée mais on dit généralement que c'est dû aux forts champs magnétiques des éclairs. Cette théorie est soutenue par le fait que les dépôts de magnétite se trouvent ...
