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

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 ...

They follow the magnetic field lines and, therefore ... but they have a higher density and produce an electric current that surrounds the Earth. Electrons move from the twilight zone to the ...

Advanced materials with finely tuned electric and magnetic properties ... and could allow us to achieve magnetic field observations with atomic-level resolution.” ...

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

Researchers found that exposing mice with type 2 diabetes to static electric and magnetic fields increases insulin sensitivity and lowers blood sugar. The paper “is a noninvasive way of treating ...

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 ...

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 ...

Bar magnets and horseshoe magnets are two of the most common shapes of magnet. The magnetic field is shown by lines with arrows that point from north to south. You can tell how old some coins are ...

the angle at which magnetic field lines intersect the Earth. The turtles use these two pieces of information, which vary at every point on the planet's surface, as navigational markers that help ...

With today’s data rates of only a few hundred megabytes per second, access to digital information remains relatively slow.

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?
