Discover how a rotating coil placed in a magnetic field generates an induced EMF. This video explains the core physics behind electromagnetic induction, showing how motion, magnetic flux, and ...

Researchers have found that exposing a certain class of particles -- micron-sized beads endowed with a special magnetic sensitivity -- to a rapidly alternating, rotating magnetic field causes them to ...

In the supplemental material the experimental setup is shown (see top image), which is designed to make the individual iron-coated polymer particles rotate. The particles are called Janus particles ...

Deep beneath our feet, far below the crust and mantle, Earth is quietly sending out a slow magnetic heartbeat. Every seven ...

Ancient volcanic rocks reveal how two giant hot regions beneath Africa and the Pacific have shaped Earth's magnetic shield.
