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 ...

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 ...

Ziad Melhem outlines the thinking that went into the design and development of the world’s most powerful all-superconducting magnet All together: The 32 T magnet lowered into its cryostat. (Courtesy: ...

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. Magnetic fields generated ...

Not long before compact discs (CDs) came on the scene, soon to be eclipsed by digital MP3 media, vinyl records were the preferred method of storing and playing music. Although they’re no longer center ...

A new world record has just been set: the generation of a continuous magnetic field of 38 tesla in a resistive (i.e. non-superconducting) magnet. Strong magnetic fields of this type are crucial for ...
