Do all the planets have magnetic fields?

On Earth we use the planets magnetic field for navigation, but there may be some planets where you would get lost. read more

Only two planets have no permanent magnetic field. In order: Mercury has a magnetic field. It's not super strong (possibly because it rotates fairly slowly), but it does exist. Venus does not have a magnetic field. We're fairly sure the core is liquid metal, so for some time scientists believe it lacked a magnetic field because it rotated too slowly. read more

Planetary magnetic fields are produced by churning motions of liquids at a planet’s core that conduct electricity and have an electric charge. The magnetic fields act like giant bar magnets and can be offset from the rotation axis of a planet. For example, the Earth’s magnetic field is tilted about 11 degrees to the axis of rotation. read more

All planets don't have magnetic fields. A planet's magnetosphere is said to result from an internal dynamo (Dynamo theory). Rotations within the planetary core of fluids induce an electrodynamic effect which generates a magnetic field and maintains it. read more
