If these metals have not been turned into a permanent magnet they will still be attracted to a magnet if placed within a magnetic field. In this situation they act as a magnet - but only whilst in ...

In a recent report, British scientists claimed the earth's magnetic north pole is moving strangely towards Russia.

How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...

Scientists at the British Geological Survey have detected an unprecedented change in Earth's magnetic North Pole. According ...

The Coriolis force in the core is millions of times greater than the viscous forces of the molten metal. It is basically a ...

This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the ...

David Bressan is a geologist who covers curiosities about Earth. Without its magnetic field, life on Earth would not be possible since this shields us from harmful cosmic radiation and charged ...

Magnetic couplings are non-contact couplings that use a magnetic field to transfer torque, force or movement from one rotating member to another. The transfer takes place through a non-magnetic ...
