In this situation they act as a magnet - but only whilst in the magnetic field. This is called induced ... are invisible but they fill the space around a magnet where the magnetic forces work ...

Magnetic cilia—artificial hairs whose movement is powered by embedded magnetic particles—have been around for ... use of "soft" magnets, which do not generate a magnetic field but become ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

As it turns out, the ability to nullify the powerful magnetic field from a ... plywood discs with magnets set into the edges. These magnets alternate in polarity around the discs, and they match ...

Electrets produce a semi-permanent static electric field, similar to how a magnet produces a magnetic field ... Electrets have been around since the 1800s, and are usually produced by melting ...

The other magnetic field going around the length of the doughnut is referred to as ... fusion power can fusion become a commercially viable energy source. Twisting the magnets can also produce the ...

A material’s response to an applied magnetic field can be characterized as diamagnetic, paramagnetic, ferromagnetic or antiferromagnetic. Four-coordinate cobalt(II) complexes possess high energy ...

Magnetic fields lines are invisible but they fill the space around a magnet where ... they can attract or repel other magnets. Although we cannot see magnetic field lines, we can detect them ...
