Hands On Mineral Identification helps you to identify over 14,500 minerals! By M. Darby Dyar, Ph.D. See our DVD collection.

Earth's Magnetic Field interactive

This interactive animation lets you explore the magnetic field surrounding Earth. Drag the compass through the space around Earth to explore the shape of Earth's magnetic field. Many spacecraft have instruments called magnetometers that help scientists map out the shape of planetary magnetic fields.

(Note: If you cannot see the animation below, or it is not working properly, you may need to download the latest Flash player.)

The Earth as a Magnet

The Earth has a magnetic field with north and south poles. The magnetic field of the Earth is surrounded by the magnetosphere. The magnetosphere keeps most of the particles from the sun, carried in solar...more

Planetary Magnets

The Earth has a dipole magnetic field. This is when magnetic field lines point in a direction out of the South Pole and into the North Pole. Planets can also have quadrupoles (4 poles) and octupoles (8-poles)....more
