Most electromagnetic actuators are rotating motors, or some variation on the theme, like servos. However, it’s possible to do linear actuation with electomagnetics, too. [Adrian Perez] demonstrates ...

Are multiple H-coils needed to accurately measure magnetic field strengths? Scientists examine the benefits of the double H-coil and single H-coil methods to measure magnetic field strengths with ...

Numerous test-and-measurement applications require a high-frequency magnetic field. Oftentimes, high field strength is needed. Examples of such applications include bio-medicine research on the effect ...

BOSTON – Magnetic fields generated by microscopic devices implanted into the brain may be able to modulate brain-cell activity and reduce symptoms of several neurological disorders. Micromagnetic ...

Researchers deploy an array of microscopic coils to create a magnetic field and stimulate individual neurons. The magnetic field can induce an electric field in any nearby neurons, the same effect ...

Little Big Coil: the record-breaking magnet is the size of a toilet roll core. (Courtesy: Stephen Bilenky/National MagLab) The highest continuous magnetic field ever created in the lab has been ...
