stand facing north, than turn around to face south. Did you notice the reversal of the horizontal component of the magnetic field?
(5) Most geophysical processes are not affected. The magnetization imprinted on solidifying lava will of course reverse direction, causing (for instance) the magnetic striping of the ocean floor. 110. Magnetometers and MRI I am just working on a presentation about geoarcheology and found your site very useful to understand the fluxgate magnetometer. However, there is one issue where I’ve trouble to follow, you write: ” Materials exist–certain ferrites–where saturation occurs abruptly and completely, at a stably defined level. If a large enough alternating current is driven through a coil wrapped around a core of such material, the core’s magnetic polarity flip-flops back and forth, and saturation occurs in each half of the cycle, in symmetric fashion.” I’ve a materials science background but never had much to do with magnetic materials, but if I think of the magnetic hysteresis loop if I come close to the saturation magnetisation the variation in applied field causes only a small var
