The detail that a force exists on a wire carrying a current in a magnetic field has an interesting application when we consider a current carrying loop. When the area vector is at right angles to the ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field ...

Ampère was playing with wires when he discovered a fundamental law of electromagnetism. Hans Christian Oersted had just discovered the connection between electricity and magnetism. Meanwhile, a French ...

This article discusses the methods on reducing common-mode field interference (CMR) when employing the ACS724 and ACS780 current sensor integrated circuits (ICs). These current sensors have integrated ...
