How To Make A Galvanometer !exclusive! -

If you are using enameled magnet wire, the insulation is transparent but non-conductive. You must remove it to make electrical contact.

The device operates on the principle of , first observed by Hans Christian Ørsted. When an electric current flows through a wire, it generates a magnetic field around that wire. By coiling the wire many times, this magnetic field is concentrated. If a permanent magnet (like a compass needle) is placed near this coil, the magnetic field produced by the current exerts a torque on the magnet, causing it to deflect. The degree of this deflection indicates the strength of the current. Required Materials how to make a galvanometer
