The Core Dynamo

Jeffrey Barker, Binghamton University, Department of Geological Sciences and Environmental Studies

This demonstration of the Earth's magnetic field requires a DC motor, ammeter, electromagnet, and DC power supply or battery. The site explains the concept of a dynamo and how if an electrical conductor is in motion within a magnetic field, a current will be generated in the conductor, and if that current flows around in a loop, it will, in turn, generate a magnetic field.
