Detailed Description
This instrument measures the remanent magnetic moment of rock specimens with a practical sensitivity from 1 emu to 5 x 10-8 emu. The magnetometer is housed in our shielded room. This apparatus represents the latest iteration of our automated sample handling capability. In 2008, a major upgrade was guided by Prof. Joe Kirschvink (Caltech) and members of RAPID (Rock- and Paleo-magnetic Instrument Development), a consortium of paleomagnetists in academia and government. Our latest instrument represents the evolution of that now-classic ‘snake-chain’ design.
