Magnetic Earth Interactive Resource
NASA's EZIE (Electrojet Zeeman Imaging Explorer) mission will use three CubeSats to map Earth's aurora electrojets, intense electric currents that flow high above Earth's polar regions when auroras glow in the sky. As the trio orbits Earth, each satellite will use four dishes pointed at different angles to measure magnetic fields created by the electrojets.

An in-depth animation provides information on the magnetic field that surrounds Earth and its role in creating northern lights, and an interactive activity allows students to experiment with magnetism.
