The Earth And Its Magnetic Field (1969)

Extending millions of miles into space, the earth's magnetic field can be measured on the earth's surface in terms of declination, inclination, and intensity. Models and animation explain theoretical causes of the field, why it affects compasses and why the magnetic poles seem to have shifted over the eons. We digitized and uploaded this film from the A/V Geeks 16mm Archive. Email us at footage@avgeeks.com if you have questions about the footage and are interested in using it in your project.
