The galvanometer was augmented by the operation of the needle of a magnetic compass when it is brought to the electric wire. The Danish physicist and chemist first discovered in the year 1820 a small amount of current and a measurable device to create a magnetic field called ‘Hans Christian Ørsted’.
The first connection was between electricity and magnetic. Today in our article we will talk about why a galvanometer is built What is its working principle, its use, and much more.
