This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

The Earth’s magnetic field briefly collapsed, leaving life on Earth exposed to increased solar and cosmic radiation. This ...

Eddy currents are specialized electric fields that are generated in the presence of a magnetic field and are often seen as a secondary field. An Eddy current can be produced by both electromagnets and ...

Researchers show that Cartan's First Structure Equation, which relates to edge and screw dislocations in crystal lattices, can be recast in the same form as a basic mathematical formula that governs ...

Lasers can investigate magnetism in non-magnetic metals and assess control of ultra-thin semiconductors using pulses of ...

So-called cracks in the Earth's magnetic field have led to spectacular aurora light shows being seen in the skies, despite there not having been a solar storm to generate them. According to ...

European eels use an electromagnetic “sixth sense” to navigate during their long migration, two new studies propose. The electrical “shadow” of a new moon may help eels cross the continental shelf of ...

A recent sudy has found that prolonged exposure to magnetic fields is linked to childhood leukemia. Examples of sources of magnetic electromagnetic fields include high voltage power lines, electric ...

A recent study published inScience Advances reveals that a temporary collapse of Earth’s magnetic field, known as the ...
