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.

SAILORS have long known that the magnetic North Pole wanders about a lot but it could be the ocean currents making it happen.

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 ...

A Magnetic Shift. Magnetic north is not fixed like its geographic counterpart, the North Pole. Instead, it meanders, driven ...

This changing magnetic field then induces an electric current in another loop. Also, the more loops you have (in both coils of wires) the greater the effect. Here is simplest version of wireless ...

The reason behind the shifting North Pole is molten iron and nickel movement in the planet's outer core. Over the last 20 years, the iron and nickel have been flowing away from the magnetic lobe ...

It can easily be seen in Figure 2 that a hot loop isn’t an independent current loop. Rather, it’s only a virtual current loop composed of the components of two real current loops. Figure 3 ...

Although the geographic poles of the Earth (the two ends of Earth's rotation axis) remain by-and-large at the same location over a long period of time, Earth's magnetic poles are known to migrate, ...

The magnetic north pole is now north of Canada’s Arctic islands, hundreds of miles south of the geographic north pole. It drifts more than 25 miles each year, and seems to be headed for Siberia.

Your navigation system just got a critical update, one that happens periodically because Earth’s magnetic north pole keeps moving. Here’s what to know.

The reason behind the shifting North Pole is molten iron and nickel movement in the planet's outer core. Over the last 20 years, the iron and nickel have been flowing away from the magnetic lobe ...
