Intensity of the Earth's magnetic field: Evidence for a Mid
Abstract. The Mesozoic Dipole Low (MDL) is a period, covering at least ∼80 My, of low dipole moment that ended at the start of the Cretaceous Normal Superchron. Recent studies of Devonian age Siberian localities identified similarly low field values a few tens of million years prior to the Permo-Carboniferous Reverse Superchron (PCRS).

Magnetic field strength | Definition, Formula, & Units
magnetic field strength, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre. The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual magnetic field ...

Because low-intensity magnetic fields do not directly trigger neuronal firing, we argue that the magnetic field itself, acting, at least in part, through cryptochromes, activates a broad range of cellular events. This demonstration of direct action of the magnetic field requires a shift from current thinking, in which magnetic induction of ...

Self-assembly of liquid crystalline block copolymers (LC BCPs) in the presence of a magnetic field, for example, can result in highly ori-ented microstructures due to the LC BCP's anisotropic magnetic susceptibility. We show that such oriented mesophases can be produced using low-intensity fields (<0.5 T) that are accessible using permanent ...
