Magnetic field due to current-carrying coil When a current flows in a wire, it creates a circular magnetic field around the wire. This magnetic field can deflect the needle of a magnetic compass.

Circular plates of copper sheet metal are stamped with cooling holes; insulators with the same pattern are placed between the plates and stacked to make a coil. Voltage is then run across the coil and ...

THE use of two equal and co-axial circular coils of wire, separated by a distance equal to their common radius and traversed by the same electric current in the same sense, has long been the ...

The researchers tested a DJI Mavic Pro 2 drone under simulated power line conditions. They sent electricity through large coils to generate magnetic fields similar to those around real-world power ...

A compass does not point directly at the physical location of magnetic north. It is oriented along the Earth's magnetic field lines at its location.

Dancing turtles have proved for the first time that some animals use Earth's magnetic field to create a personal map of their favourite spots, according to scientists.

A dazzling new image depicts the magnetic field lines that snake around the sun.

Astronomers have mapped the magnetic fields of the Local Bubble surrounding our solar system in 3D for the first time ever.
