But if the charged objects are moving, they can also create and experience a magnetic force. One way to get moving charges is to run electric current through a wire. (This is literally a stream of ...

When an electric current passes through a metal ... which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the geomagnetic ...

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 ...

A controversial new study has claimed that it is possible to generate electricity using the Earth's rotation, its magnetic field, and a surprisingly simple device. If replicated, that could be pretty ...

"Among various materials, helimagnets are particularly interesting because they exhibit chirality through their magnetic structure ... where electric current flows more easily in one direction ...

Any movement of a conductor through this magnetic field does indeed produce a force on the electrons within it ... Now Chyba and co have shown that such a conductor can extract electrical energy ...

Where does the force come from? Electric currents and magnetic fields are closely related. If you have one, you often have (or can make) the other. The braking force in the demonstration is due to ...

it moves parallel to the magnetic field, producing no force. This would tend to make the motor come to a stop, but two features allow the coil to continue rotating: This means that the current in ...
