New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

Magnetism and electromagnetism occur because of the magnetic fields around magnets and around electric currents. BBC Homepage. ... Magnetic fields - CCEA Magnetic field of a bar magnet.

The magnetic field around a circular loop of wire is similar to that of a bar magnet. When an electric current flows through the loop, it generates a magnetic field.

Cutting a bar magnet in half won't get rid of its poles. It'll just produce two magnets, each with a north pole that will be attracted to the other magnet's south pole, and vice versa. It's this ...

If you’ve ever found yourself wondering how those tool magnetizer/demagnetizer gadgets worked, [Electromagnetic Videos] has produced a pretty succinct and informative video on the subject. Wh… ...

This magnetic field is very similar to the field that is produced by a common bar magnet. It is called a dipole because it has two poles at either end of the magnet. These endpoints are where the ...

On August 12, the hybrid magnet produced a record-breaking steady-state magnetic field of 45.22 T with a power input of 26.9 MW. Of that, the resistive magnet contributed 34.22 T, with the ...

The hybrid magnet at the Steady High Magnetic Field Facility (SHMFF) in Hefei, China set a world record for the highest steady magnetic field by a working magnet when it produced a steady field of ...

That is over 800,000 times stronger than the magnetic field produced by Earth ... record of 41.4 tesla held by another resistive magnet at the National High Magnetic Field Lab in Florida ...

That magnet is strong, representing roughly 75 percent of the intensity of Earth's magnetic field at the surface. Of course, a bar magnet is not a perfect representation — it's actually electric ...

In order to track the Earth's magnetic field, scientists treat it as if it were produced by a bar magnet, and then compare those results to the actual observed magnetic field.
