Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...
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 ...
New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...
Two German physicists have unveiled a compact magnet layout that outperforms the famed Halbach array, delivering stronger, ...
Magnetic levitation — bismuth's ability to seemingly float between two magnets — is perhaps one of the most interesting. The repulsion between bismuth and the magnets is so strong, it causes ...
Save guides, add subjects and pick up where you left off with your BBC account. A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron ...

They found that the magnetic field of the rotor magnet exerted some amount of torque on the floater resulting in the two magnets rotating in sync due to a gyroscopic effect.
Earth’s magnetic field has correlated with fluctuations in atmospheric oxygen, according to a newly released study.
They also found that when they swept an external magnetic field up and down, the flakes could be switched between two different superconducting states, just like a magnet.
Resistive magnets can create fields much more powerful than superconducting magnets, but the two together form a magnetic dream team. CHMFL’s 45.22 tesla hybrid magnet is the most powerful of ...
As a result, ferromagnetic materials can be easily magnetized when exposed to a magnetic field. Materials like iron and magnetite, an oxide of iron (Fe 3 O 4), naturally have their magnetic fields ...
