This video explains how magnets work and how magnetic fields are generated by the movement of electric charges. Magnetic ...

Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New ...

A magnetic field is the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it ...

An electric charge (like a proton) creates an electric field in the region around it. This field points away from positive charges and decreases in strength as it gets farther away from the charge.

Like a shaggy dog in springtime, some black holes have to shed. New computer simulations reveal how black holes might discard their magnetic fields. Unlike dogs with their varied fur coats, isolated ...
