Magnetic remanence is often identified with a particular kind of remanence that is obtained after exposing a magnet to a field at room temperature. However, the Earth's field is not large, and this kind of remanence would be weak and easily overwritten by later fields. A central part of rock magnetism is the study of magnetic remanence, both as natural remanent magnetization (NRM) in rocks obtained from the field and remanence induced in the laboratory. Below are listed the imp… Web1 day ago · Experts at the University of Alberta recommend these four tests: Check if the specimen feels unusually heavy for its size, test its magnetism using a refrigerator magnet, check for holes and bubbles, and examine the outer layer for a thin, black eggshell-like crust.
