At the same time, a moving charge makes a magnetic field (B), and other moving charges experience a force in that field. Let's see how this plays out in a couple of situations. First, suppose we ...

A study using the Very Large Array radio telescope may have discovered a magnetic field on exoplanet YZ Ceti b. Magnetic fields protect planets from energetic particles that can strip away ...

Nearly two centuries after Faraday's failed attempts, scientists have demonstrated that Earth's continuous spin can directly ...

A controversial new study has claimed that it is possible to generate electricity using the Earth's rotation, its magnetic ...

(a) Schematic illustration of a typical magnetic metasurface used for magnetic field concentration indicating the main geometrical parameters and the applied magnetic field orientation. (b) False ...

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...
