Connect the battery and resistor in series across the terminals.
: Briefly touch the two bare ends of the wire to the positive and negative terminals of your battery. how to make a galvanometer
When you touch the wires to the battery terminals, observe the compass needle. Connect the battery and resistor in series across
Making a galvanometer is a classic science project that demonstrates the fundamental relationship between electricity and magnetism. By passing current through a wire coil, you create a magnetic field that interacts with a magnetized needle, causing it to move. causing it to move.
