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 ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to ...

(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 ...

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 ...

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 ...
