Marie Ampère, who died on June 10, founded electromagnetism after a spark of inspiration in 1820, changing physics forever.

Beneath Earth s surface, nearly 3,000 kilometers down, lies a mysterious layer where seismic waves speed up inexplicably. For ...

See all that stuff around you ... have two parallel wires carrying electric current in the same direction. Since wire 1 has moving charges, it creates a magnetic field. Wire 2 is in the presence ...

A superconducting wire segment based on rare-earth barium copper oxide (REBCO) is the highest performing yet in terms of current density, carrying 190 MA/cm 2 in the absence of any external magnetic ...

To resume briefly, any points around the wire have a scalar (non-vector) magnetic field value. The three vectors associated to that point are: magnetic (M), attraction (A) and current (C) field ...

The magnetic field around a straight wire is circular and follows the right-hand rule. When an electric current flows through the wire, it generates a magnetic field concentrically surrounding the ...

We implement a computational approach, that is based on iterating n times the magnetic field produced by a finite current-carrying wire, to evaluate the magnetic field at any point in space for coils ...

Since a magnetic field is produced around a current-carrying conductor ... was put out on the wire going to the fuel filter by-pass sensor. When an actual by-pass occurred, the sensor switch ...

The more electric current a device uses, the stronger the magnetic field will be. It might be surprising to learn just how varied magnetic field levels are around products. The strength of a ...

of the electromagnetic spectrum An electric field is created whenever you plug a wire from an electrical product, like a lamp, into an outlet. When you turn the lamp on, the flow of current, known as ...

Place your right hand with the thumb parallel to the wire carrying the current. Point your thumb in the direction ... Your fingers will now point in the direction of the magnetic field around the wire ...
