A New Theory of Magnetic Storms

A New Theory of Magnetic Storms is a 1931 book by Chapman and Ferraro which seeks to explain geomagnetic storms.

This book argues that whenever the Sun emits a solar flare it will also emit a plasma cloud. This plasma will travel at a velocity such that it reaches Earth within one day. The cloud will then compress the Earth's magnetic field and thus increase this magnetic field at the Earth's surface. It is now understood that the Sun continually emits plasma in the solar wind and that this phenomenon is amplified whenever solar flares occur.
