Simple Experiments to Study the Earth's Magnetic Field

摘要

Aset of simple experiments is outlined for determining the magnetic field of the Earth. These experiments can be performed by students from high school to college and will help them gain a greater appreciation of the three-dimensional nature for the Earth's magnetic field. Reasonably accurate measurements of the field strength, its components, and dip angle are possible through use of a transparent solenoid, a compass, and a Magnaprobe.
