DT Science House Tangent galvanometer for physics Lab experiments

About this item

• Instrument: A tangent galvanometer is an instrument used in physics laboratories for measuring electric current.
• Principle: It works on the principle of tangent law, which states that the deflection of the needle is proportional to the tangent of the angle between the needle and the magnetic meridian.
• Construction: It consists of a circular coil of wire with a small compass needle suspended at its centre.
• Measurements: When an electric current flows through the coil, it creates a magnetic field that deflects the compass needle, allowing the measurement of the current.
• Applications: Tangent galvanometers are commonly used in experiments to study the properties of electric currents and magnetic fields.
