The direction and intensity of remanent magnetism has been measured on a series of iron meteorite specimens and their magnetic domain patterns have been studied on polished surfaces. Specimens were carefully collected in the field and their geographic orientation noted. From these specimens, the magnetic effects of the geomagnetic field could be estimated and only those specimens which lacked such effects were used for further study. Specimens obtained from museums or similar sources are not considered satisfactory for these magnetic studies.
The intensity of remanent magnetism for octahedries from Arizona Crater averages 11.6×10-3emu/cm3, whereas that for octahedrites from odessa Crater averages 6.6×10-3emu/cm3. Domain patterns for schreibersite have a chain-like cross-section and are rod shaped in longitudinal section. Kamacite has a rectangular pattern when carefully prepared or under other conditions, a maze pattern.
