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 ...

High frequency Helmholtz coils are often used to generate uniform but time varying high frequency magnetic fields for a number of applications such as magnetic field susceptibility, calibration, and ...

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 ...

Massachusetts General Hospital (MGH) researchers have developed what appears to be a significant improvement in the technology behind brain implants used to activate neural circuits responsible for ...

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 ...

Scientists are pursuing the proposition of clean and inexhaustible power from nuclear fusion through a variety of experimental reactor designs, and one of the more interesting examples is a roughly ...

There are more pieces of plastic in the ocean than stars in the Milky Way galaxy. Up to 14 million tons of plastic enters the ocean annually, 40% of which is considered "single-use," which means it ...
