A 1912 experiment found that if an electromagnet spins on its long axis, its magnetic field does not rotate along with it. And while the Earth spins, its rotational axis doesn’t quite line up ...

^ to top. What's going on? The fundamental fact that every electric current always generates a magnetic field is called Ørsted's law. The Danish scientist Hans Christian Ørsted (1777-1851) made ...

"If the effect is real and scaling behaves the way our equations say, then the possibility becomes real," Chyba told Newsweek ...

This will create a magnetic field, and other wires with electric current will experience a magnetic force. Imagine you have two parallel wires carrying electric current in the same direction.

Faraday’s Law of Induction describes how an electric current produces a magnetic field and, conversely, how a changing magnetic field generates an electric current in a conductor.

Electric Currents Make Magnetic Fields. Here is a simple experiment. You probably have the materials so that you can try this at home. Well, you might not have a magnetic compass - but you should ...

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 ...

The electrical current then generates a force that pushes against the tether, and depending on the orientation of the tether to the magnetic field, the force will either speed up or slow the ...

But Faraday’s experiments were a resounding failure and a few years later, physicists worked out why. Any movement of a conductor through this magnetic field does indeed produce a force on the ...
