“The electric and magnetic fields at a material’s atomic level determine its bulk properties and behavior, and are an essential area of research,” says Toshiaki Tanigaki, a senior researcher ...

It looked still to you before because you were moving with it. We have this same problem with electric and magnetic fields. Depending on your reference frame, what appears to be a magnetic force ...

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 ...

When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by ...

The electric field is “an agent of chaos ... Models show that our magnetic field can trap these particles and push them back ...

Nearly two centuries after Faraday's failed attempts, scientists have demonstrated that Earth's continuous spin can directly ...

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...

Get Instant Summarized Text (Gist) Micrometer-sized, flower-shaped structures made of a nickel-iron alloy can locally enhance magnetic fields by concentrating field lines at their center. The ...

How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...
