Generated by internal dynamos, magnetic fields are one of the few remote sensing means of constraining the properties of planetary interiors. The Earth's magnetic field has been speculated to be partially responsible for its habitability, and knowledge of an extrasolar planet's magnetic field may be necessary to assess its habitability.
