Coil Whine Is Annoying, But Generally Harmless The exact origin of coil whine lies in the electromagnetic coils present in your PC's components, particularly the graphics card and power supply.

State-owned arms maker China South Industries Group (CSGC) has released footage of its electromagnetic coil gun. Allegedly capable of firing 3,000 rounds per minute, the prototype represents a ...

The design uses a coil of copper wire in a 3D-printed plastic housing, surrounded by a claw full of strong magnets. When the coil is activated, the magnets are pulled towards the coil.

In the generating station, a computer shows "Gauss field phasing adjustment for coil form deterioration" with electromagnetic fields counting down from 200 EMF to around 150.

A tube is placed inside a coil, with the end fitting then installed inside. A capacitor bank dumps current through the coil to generate a strong electromagnetic field.

Collisions of heavy ions generate an immensely strong electromagnetic field. Scientists investigate traces of this powerful electromagnetic field in the quark-gluon plasma (QGP), a state where ...

OSU researchers developed a new kind of dart launcher that uses electromagnetic coils to propel the dart, as well as a laser rangefinder to calculate exactly how much force is needed so the dart ...

In strong electromagnetic fields, “how QED has to be calculated completely changes from how it’s done in low fields,” says Lötzsch, of Friedrich Schiller University Jena in Germany.

Learn about who can benefit from repetitive transcranial magnetic stimulation (rTMS), how it works, and what it feels like.

Coil whine is a completely normal part of electronic component operation. All it means is your computer is working very hard, and there's nothing to be worried about.
