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 ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

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 ...

(A) Fabrication process of the shaftless propeller-like millirobot, including positive structures’ fabrication by 2-photon polymerization (2PP), negative mold fabrication and casting process of the ...
