Strong Magnetic Field
A magnetic strong-field-seeker trap for cold neutral atoms was demonstrated in two experiments: in 1991 by guiding an effusive beam of thermal sodium atoms (mean velocity ~600 m/s) along a 1-m long current-carrying wire (Schmiedmayer, 1992, 1995a,b) and in 1998 with cold lithium atoms loaded from a MOT (Denschlag et al., 1999b).

While the strong magnetic signatures in the Apollo samples stuck out like a sore thumb, weaker signatures have received less attention, Evans says. The presence of those weak signatures along with the strong ones would give this new idea a big boost, which could finally put the Moon's magnetic mystery to rest.

In a strong magnetic field, some walls disappear entirely. The resulting magnet's strength depends on the amount of force used to move the domains. Its permanence, or retentivity, depends on how difficult it was to encourage the domains to align. Materials that are hard to magnetize generally retain their magnetism for longer …
