# Interaction of geomagnetism on free falling coil

Take the Earth, or a similarly large body with an Electromagnetic field. For now - expect atmosphere.

Then take a much smaller object - say the size of bus, containing a coil with many windings.

If meters were attached to this coil - would an EMF be induced in it, and Simplifying so the object would be travelling at terminal velocity (ignoring the initial acceleration), could this be calculated or predicted?

If the magnetic flux through the coil is changing then yes, there would be an EMF and if you knew the relevant parameters then yes, you could predict it en.wikipedia.org/wiki/… –  Michael Brown Jan 24 '13 at 9:12
