Placing materials under extremely strong magnetic fields can give rise to unusual and fascinating physical phenomena or behavior. Specifically, studies show that under magnetic fields above 100 tesla ...

As black holes feed, they pull material into a disk around them. The material orbiting in this disk gets heated to extreme temperatures, and so it becomes a plasma — a state of matter in which some of ...

A huge region of molten iron deep beneath the Pacific Ocean suddenly changed direction around 2010. The discovery suggests ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

This video explains how a DC generator works. It differs from an AC generator because it has a split ring commutator, which switches the connection every half turn and keeps the current flowing in one ...
