A supercooled microscopic ferromagnet proves the existence of gyroscopic magnetic behaviour that has been long sought by ...

Solve the falling wire problem to find terminal velocity in a magnetic field. See how motion through a magnetic field induces an emf and current, creating a magnetic force that opposes the fall ...

For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon ...

This study focuses on the direct-drive ultrasonic resonant motors called PILine ® motors. Their direct-drive design enables ultra-low response times and highly precise positioning without any backlash ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...

Earth’s magnetic field nearly collapsed long ago. What saved it explains why life survived and why the planet remains ...

The Sun is governed by a strict rhythm. The magnetic activity of the Sun displays a cyclic variation, reaching a maximum approximately every eleven years. Two enormous plasma circulations, each in one ...

(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 ...
