Understanding the longevity of Mars’s dynamo is key to interpreting the planet’s atmospheric loss history and the properties of its deep interior. Satellite data showing magnetic lows above many large impact basins formed 4.1-3.7 billion years ago (Ga) have been interpreted as evidence that Mars...

The models showed these deep-geological climates emerging first from the center of continents and then expanding outward over time. Temperatures rise, precipitation increases, ice caps melt and climates become temperate near the Earth's poles. ...
Magnetic PolesMagnetic Field ConfigurationsMagnetohydrodynamicsPaleomagnetismSolid State PhysicsA PRIMARY task of geomagnetism is to account for the magnetic field of the Earth and for the occasional reversals of that field. Present research in geomagnetic dynamo theory aims to develop a physically realistic...
The invention discloses a reversing direct-current motor with magnetic poles formed by combined permanent magnets, and belongs to the field of motors. The reversing direct-current motor is mainly used for solving the problem that inductive counter electromotive force is generated when a direct-...
