Experiments suggest an unusual magnetic material could help harness energy from Earth’s rotation. But not everyone is ...

With a new measurement imminent, the Courier explores the experimental results and theoretical calculations used to predict ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

They demonstrated that the fields representing the strain generated around lattice dislocations in crystalline materials, modeled by Cartan's First Structure Equation, obey the same equations as ...

Building bridges in physics Date: March 10, 2025 Source: Osaka University Summary: Researchers show that Cartan's First Structure Equation, which relates to edge and screw dislocations in crystal ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear ...

Recently, however, it has come into its own, and now occupies a central place in several of the most vibrant frontiers of modern physics. Dirac's equation connects the four components of a field ψ.
