If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions ...

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

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 ...

Over two centuries ago, physicist Michael Faraday described how electric current running through a coil of wire can create a magnetic field. This magnetic field can then induce an electric field ...

Scientists know well how conventional materials conduct heat. However, things are not as straightforward under extreme ...

Pictures may enliven us, but other data, such as information about magnetic fields, add a huge amount to our understanding of ...

This is called electromagnetic induction close electromagnetic inductionThe production of a potential difference (voltage) when a conductor, such as a wire, is moved through a magnetic field or ...

Getting a magnetic field to balance on another magnetic field ... with each winding getting about 800 turns of enameled wire. The rest of the circuit is straightforward. It appears he uses a ...

Quasiparticles are collections of particles (and, in some cases, field lines) that can be described mathematically as if they were a single particle with properties that are distinct from their ...

Merging some esoteric physics principles with an advanced instrument creates a magnetic microscope with resolution better ...
