Magnetic effect of electric current is one of the major effects which functions as the basic principle in appliances used in various fields of activities. The magnetic field around a current carrying ...

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 ...

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 ...
