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

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 ...

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

A substorm should come with violent electric currents and magnetic field fluctuations, but MMS spotted traces of neither. "We have not looked at the movement of the magnetic field lines on a ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

Reader Jayant Bhalerao, a college physics instructor, found the story useful in class: “We will share it with our students, so that they can appreciate how ...

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 ...

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 ...

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 ...

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

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 ...

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?
