Moving coil galvanometer

A device used to measure electric currents even as low as a few microamperes is known as a galvanometer. Generally, there are two major types of galvanometer – one with suspended coil and another with pivoting coil or a Weston galvanometer. When an electric current is made to pass via a conductor, a deflection in […]

Faraday’s law According to this law an induced EMF is generated in a conductor when it is placed in a variable magnetic field. In mathematical form, it can be given as  E = -t Here is change is magnetic flux in small time period t. Experiment 1 The first experiment of Faraday helps us understand
