Magnetic Effects of Current

Lenz’s law states that the direction of the induced electric current by a changing magnetic field in a conductor in such a way that the induced current creates a magnetic field that opposes the changes of the initial magnetic field. It was named after Emil Lenz who stated this law in 1834. Lenz’s law has […]

The force of attraction or repulsion between two straight and parallel current-carrying conductors or wires is often called Ampère’s force law. The physical origin of this force is given by the idea that every current-carrying wire generates some magnetic field, following the  Biot-Savart law, and the other wire experiences some magnetic force as a consequence,

In 1820, two French scientists Jean Baptiste Biot and Felix Savart experimented with the interaction between an electric current and a magnetic field.  Every magnetic field is produced by a current and the intrinsic magnetic movements of the particles. Thus the relation between the arbitrary current and magnetic field is referred to by the Biot-Savart
