The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM ...

The Steady High Magnetic Field Facility (SHMFF) in Hefei, China, has successfully developed a resistive magnet that surpasses ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...

By simulating a magnetic field on a superconducting quantum computer, researchers can explore the intricate properties of ...

A prestigious physics paper was once co-authored by a Siamese cat for a very key reason in 1975. And no, we're not joking.

The Earth has a magnetic field, generated by processes from deep within the planet. Molten metallic material flows in the outer core, and as it cools, convective forces create movement ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

Since the launch of the Large Hadron Collider, there has been ongoing research there into Higgs bosons and a search for traces of physics beyond ... how Earth's magnetic field may be influencing ...

Magnetic devices are components for creating, manipulating or detecting magnetic fields. This can include magnetic memories, magnetometers and devices for magneto-optics. Magnetism can also play a ...
