MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field ... around this time. This naturally occurring pigment, rich in iron oxide, has long ...

far out in the long "tail" of Earth’s magnetic field. (Our planet's magnetic field should look a lot like the field around a bar magnet, but electrically charged particles in the solar wind push ...

Grab a roll of aluminium foil that is at least 30 metres, preferably 50 metres and better yet 150 metres long (these ... flowing through a straight wire generates a magnetic field.

This article is based on a recent model specifically defining magnetic ... the wire. Its magnitude is equal to I/r. Letter A stands for: Attraction. Moreover, Figure 1 is a very general case of moving ...

The magnetic field around a straight wire is circular and follows the right-hand rule. When an electric current flows through the wire, it generates a magnetic field concentrically surrounding the ...

“Solar observations have given us a good idea for how material moves around inside of the Sun. For our supercomputing calculations, we solved equations to determine how the magnetic field ...
