The phenomena of electricity and magnetism were important subjects of research by physicists in the nineteenth century. Both phenomena exhibited an inverse square law dependence of force and distance. Both phenomena exhibited poles. Some physicists suspected a relation between electricity and magnetism. It was not until 1820 that Hans Christian Oersted experimentally and conclusively proved

According to the superposition theorem, the response across each element in a linear, active, bilateral network with more than one source is the sum of the responses obtained from each source evaluated independently, and all other sources are replaced by their internal resistance. When two or more sources are present and connected, the superposition theorem

The galvanometer is a device used to measure the electric current’s presence and determine small current’s magnitude. This instrument detects the small electric current by showing deflection in the needle present inside the galvanometer. It is used in bridges and potentiometers where it indicates zero electric currents. When does the galvanometer show a deflection? Besides

The law of conservation of energy and Lenz’s law are closely related to each other. The conservation of energy involves the application of Lenz’s law. It states that energy cannot be created or destroyed, but it can be converted into another form. According to Lenz’s law, the direction of the current opposes the magnetic flux’s

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
