Product details A terrella
A terrella
A terrella ('little earth') is a sphere made of a magnetized substance, used to simulate the magnetic field of the earth. In the 16th century the English physician William Gilbert used a terrella made out of lodestone (a naturally-occurring magnetized mineral) to demonstrate that the earth is magnetic, and to explain how mariner's compasses work.
