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 ...

Likewise, a wire passing through a magnetic ... which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the geomagnetic dynamo.

materials and would feel the force from a nearby magnet. All other materials that ... one that is generated when a current flows through a wire. Electromagnets can therefore be switched on and ...

The induced magnetic field of a wire can interact with other nearby magnets, producing a force.

The device sure looks like an electromagnet made with magnet wire and a steel core ... The two fields combine to produce a force on the metal it interacts with. This is often referred to as ...
