Product Description

SIMPLE GALVANOSCOPE

This can be used to demonstrate the working principle of a Galvanoscope while teaching Electricity in class room.This is a device to detect whether electricity is flowing through a circuit or a conductor or not.

In designing this I used a plastic container lid as a base.I took an insulated motor winding wire and 20-25 rounds or turns to make a circular coil and fixed it to the base.A sewing needle is magnetised with the help of a permanent magnet and is hung from the upper side of the coil towards to its center with a thread.When the two free ends of the coil are connected to a circuit, the deflectioni the position of  the needle, indicates that electricity is flowing through the circuit in one direction and deflection in opposite direction indicates the flow of electricity is in opposite direction. No deflection in the position of the neele means no flow of electricity.
