Learn how to calculate and understand the force on a wire loop entering a magnetic field in this detailed physics tutorial! We break down the concepts of magnetic flux, Lorentz force, and induced ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of years. Using ancient magnetic records and advanced simulations, scientists ...

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

Strontium ruthenate, SRO214, is a good example of unusual superconductivity. Its superconductive qualities were found by a research team that included Yoshiteru Maeno, who is currently at the Toyota ...
