WebKEYWORDS: dynamo theory, earth's magnetic field, planetary magnetic fields, earth's core. ABSTRACT . For nearly a century, geoscientists who believe the earth is billions of years old have been striving to develop a successful "dynamo" theory to explain how the earth's magnetic field might maintain itself over that long ime. WebThis video gives a brief introduction to magnetism and magnetic field for the Earth and Jovian planets. The dynamo theory hypothesizes that electrical current int he core of a planet creates...
WebJan 10, 1995 · For more than 200 years the origin of Earth's magnetic field was attributed to permanent magnetization. Even today no single argument (e.g., that Earth's deep interior is too hot to sustain permanent magnetization) conclusively rules out the permanent magnetization hypothesis. WebMercury's magnetic field is approximately a magnetic dipole (meaning the field has only two magnetic poles) apparently global, on planet Mercury. Data from Mariner 10 led to its discovery in 1974; the spacecraft …
