The Aarson Tangent Galvanometer for the physics lab is an essential apparatus for measuring electric currents based on the deflection of a magnetic needle. Here's a simplified explanation of its components and functions:
Bakelite Ring or Bobbin: This component, with a diameter of 165 mm, serves as the core around which wire windings are wrapped. It provides the magnetic field necessary for the operation of the galvanometer.
Windings: There are three sets of windings on the bakelite ring, each with a different number of turns: 2, 50, and 500. These windings determine the sensitivity and range of the galvanometer for measuring different strengths of electric currents.
Magnetometer: The magnetometer is supported on a brass tube, which is fitted on an ebonite plate. It can rotate independently of the base of the instrument. This setup allows for precise adjustments and alignment during experiments.
Base: The base of the instrument features levelling screws, enabling the adjustment of the entire apparatus to ensure accurate measurements. It provides stability and support for the rest of the components.
Compass Box: This component consists of a bakelite base with a metal dial, graduated in degrees with an anti-parallax mirror. The dial allows for easy reading of the deflection angle of the magnetic needle. The mirror minimizes errors caused by parallax.
Magnetic Needle and Pointer: The cobalt steel magnet and aluminum pointer are mounted on special synthetic sapphire, which reduces friction to make the needle virtually frictionless. This setup ensures precise and sensitive deflection of the needle in response to electric currents.
Overall, the Tangent Galvanometer is a versatile and accurate instrument for measuring electric currents in physics experiments. Its various components work together to provide sensitivity, stability, and ease of use for accurate measurements.
