The Hall effect has been an important tool in physics for more than a century. In 1879, Edwin Hall discovered that when a magnetic field is applied perpendicular to a material carrying an electric ...

This video explains how magnets work and how magnetic fields are generated by the movement of electric charges. Magnetic materials influence and interact with current, motion, and force, making them ...

Particle accelerators are often framed as exotic machines built only to chase obscure particles, but they are really precision tools that use electric fields and magnets to steer tiny beams of matter ...

On a breezy afternoon last autumn in Cambridge, Mass., in a laboratory thrumming with the huff-whish-huff sound of refrigeration pumps, Massachusetts Institute of Technology graduate student Jiaruo Li ...
