Iron filings are sprinkled on a bar magnet, showing the magnetic field lines.

Stars are hot balls of plasma, but astronomers have now spotted a super strange one that may have a solid surface. Its intense magnetic field is strong enough to overcome its blistering temperatures and “freeze” its outer layers into a solid crust.

The emotional information that’s modulated and coded into these fields changes their nature, and these fields can impact those around us in a variety of ways.

Scientists at a laboratory in England have shattered the record for the amount of energy produced during a controlled, sustained fusion reaction.

The "Hall effect" or "anomalous Hall effect" occurs when electric current flows through a conductor or magnet in a magnetic field, generating voltage perpendicular to the electric and magnetic field directions. Onsager's reciprocal theorem, a fundamental theorem in materials science, states that the

NASA has selected two missions to study our sun and its effects on space weather. One mission will study the sun's mechanism of sending particles and energy to the solar system.
