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 mysterious electromagnetic mechanism may be more important than the firing of neurons in our brains to explain our ...

Figure 1 Schematic diagrams of two superconducting flux qubit circuits. The conventional qubit (a) requires an external magnetic field to operate optimally, while the new flux qubit (b), using a ...

A trio of physicists, two with Coventry University, in the U.K., and the third with Laboratoire National des Champs ...

Electric brakes are devices that use an electrical ... The electrical current is sent to coils, which alternate polarities, creating an electromagnetic field. This change in magnetic flux induces a ...

Until now, all such flux qubits could only be run when enveloped in a magnetic field. In this new effort, the research team introduced the use of a ferromagnetic Josephson junction (π-junction ...

When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by ...

These convection currents rise through a pre-existing magnetic field, sparking electric currents that induce their own ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...
