NASA Is Tracking a Massive Anomaly in Earth’s Magnetic Field — And It’s Getting WorseA vast and evolving anomaly in Earth’s magnetic field, situated above South America and the southern Atlantic Ocean, ...
Russell-McPherron Effect: Why "Cracks" In Earth's Magnetic Field Mean We Get Peak Auroras At Equinox
Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the ...
Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...
Back in 1832, the celebrated British physicist, Michael Faraday, carried out a set of experiments designed to answer a tantalizing question: could electricity be generated by Earth's rotation through ...
This, in turn, affects convection in the outer core—the dynamo-like process that generates the magnetic field that protects life on Earth from harmful cosmic rays. "Flow in the outer core drives ...
The other magnetic field going around the length of the doughnut is referred to as toroidal (green horizontal circle). The combination of these two fields creates a three-dimensional curve, like a ...
