Tabletop models for electrical and electromagnetic geophysics
Department of Geological and Mining Engineering and Sciences
These tabletop models were created from common materials to demonstrate concepts in direct current electrical resistivity, self potential and electromagnetic geophysical methods. The models can be used as a laboratory exercise or as a classroom demonstration. Data profiles over the models are similar to those computed from equations and from field examples. The signals are generated with a function generator or battery and are measured with a digital multimeter. The experiment is greatly facilitated by using a multimeter that can be connected to the serial port of a computer. The tabletop models reinforce concepts learned in basic physics courses, introductory geology and geophysics courses, and in environmental engineering courses.
