Seeking to mimic self-assembly processes that occur naturally, RIKEN researchers have demonstrated that the self-assembly of ...

A new prototype is laying claim to the title of smallest, lightest untethered flying robot. At less than a centimeter in ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

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 ...

These moving, electrically charged dust grains would create a weak-but-wide-scale electrical current, like a copper wire 1,000 ... the universe's magnetic fields were like long ago, but we can ...
