New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

It’s now been around 2,600 years since the Greek philosopher Thales noticed that magnets attract iron. We understand almost completely how magnets work, right down to the detailed atomic level .

Quantum bar magnets in a transparent salt Date: June 15, 2012 Source: ... Anybody who has played with toy bar magnets at school will remember that opposite poles attract, ...

Cutting a bar magnet in half won't get rid of its poles. It'll just produce two magnets, each with a north pole that will be attracted to the other magnet's south pole, and vice versa.

Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic materials, and where they can attract or repel other magnets.

Like conventional bar magnets, the droplets’ opposite poles attract and their matching poles repel, and dividing up a single magnetized droplet produces smaller pieces with their own north and ...

From the slopes of these three lines, I can get three different magnetic dipole moments. They are: Traditional Compass: μ = 0.2207 A*m 2; iPhone Compass: μ = 0.0525 A*m 2; xSensor: μ = 0.3077 A ...
