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 ...

(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 ...

Why there’s a need to assess current-flow distribution. How an arrangement was made for the measurement using a controlled magnetic field, laser-induced current flow, and a subtle physics-materials ...

Solve a rotating-coil electromagnetism problem by deriving the induced emf from changing magnetic flux. Learn how coil area, number of turns, rotation rate, and magnetic field strength set the emf ...
