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

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 ...

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

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 ...

To calculate the force on a wire carrying a current at right angles to a magnetic field, use the equation: 2 A flows through a 50 cm wire. Calculate the force acting on the wire when it is placed ...

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.
