Controlling magnetism in a device is not easy; unusually large magnetic fields or lots of electricity are needed, which are ...

S cientists have found that it’s possible to generate electric power from Earth’s rotation through its own magnetic field ...

One way to get moving charges is to run electric current through a wire. (This is literally a stream of electrons.) This will create a magnetic field, and other wires with electric current will ...

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...

The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like ... produce an approximation of what the field lines would look like on its electronic ...

With today’s data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: Magnetic ...

This flower-shaped geometry causes the field lines of an external magnetic field to concentrate in the center of the device, resulting in a greatly intensified magnetic field. The study is ...

A magnetic field is invisible ... different positions in the magnetic field, marking the needle direction each time join the points to show the field lines The needle of a plotting compass ...

If these metals have not been turned into a permanent magnet they will still be attracted to a magnet if placed within a magnetic field ... Magnetic fields lines are invisible but they fill ...

The Analyzer for Cusp Electrons (ACE) is designed to measure electron activity in the region of the northern magnetospheric ...

At a cost not far above £10 ($13.70), this was an impulse purchase driven by curiosity; these devices claim to measure both magnetic and electric fields, but what do they really measure?
