Past and Present Magnetism of the Moon,f the field is a dynamo process in a molten, electrically-conducting core, but generation of a transient magnetic field during large meteorite impacts cannot be entirely ruled out. The magnetizing process may be thermoremanence, acquired when the rocks cooled through the Curie point of the constitue

On the Grain Size Dependence of the Behavicur of Fine Magnetic Particles in Rocks,moremanent magnetization (TRM) and its stability against AF demagnetization are interpreted in terms of nucleation theory. It is concluded that each of these parameters exhibits grain size dependence due to two effects. The first is the increasing difficulty with which domain walls are neucleated as

,S. K. Runcorn’s Commentary,ere truthfully recording the direction of the geomagnetic field at the time of formation or magnetization. More than scientific caution was involved: it seemed too good to be true that archaeological specimens from hearths and bricks, then lavas, then red sandstones, then sediments generally, then g

,S. K. Runcorn’s Commentary, me, on the measurements in deep coal mines to determine the radial variation of the geomagnetic field. Such useful experience for students and such welcome assistance with research is now virtually impossible as a result of University’s bureaucratic attitudes to temporary employment and to unionisa
