One of the many unseen forces to which you owe your existence is magnetism. If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely ...

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 atmospheres ...

Would a dramatic change in the Earth's magnetic field affect creatures that rely on it during migration? Late on a January night in 1993 I found myself on a beach on the Pacific coast of Costa ...

it produces its own magnetic field the magnetic field cannot be turned on and off – it is there all the time Bar magnets and horseshoe magnets are examples of permanent magnets.

Magnetism is caused by the fields that exist around magnets. These magnetic fields can be investigated by looking at the effects of the forces they exert on other magnets and magnetic materials.

Researchers show that Cartan's First Structure Equation links crystal defects to the same mathematical rules governing electric currents and magnetic fields.
