Tangent Galvanometer
Tangent Galvanometer is a classic and essential apparatus in physics laboratories, designed for the accurate measurement of electric current and verification of the tangent law of magnetism. This device consists of a circular coil of insulated copper wire mounted vertically, with a compass box placed at its center. When current flows through the coil, it generates a magnetic field that interacts with the Earth’s magnetic field, causing the magnetic needle in the compass to deflect.
By measuring the angle of deflection, students and researchers can determine the current passing through the coil using the tangent law formula. Its robust construction, clear scale markings, and precise compass mechanism make it ideal for educational demonstrations, experimental verification of magnetic principles, and current calibration.
Features:-
- Circular Coil Construction – Made of insulated copper wire wound into a perfect circle for uniform magnetic field generation.
- Sturdy Non-Magnetic Frame – Ensures the instrument’s structure does not interfere with the magnetic field.
- High-Quality Compass Needle – Sensitive magnetic needle mounted at the center for precise deflection measurement.
- Graduated Scale – Marked in degrees for accurate reading of needle deflection.
- Multiple Coil Turns – Usually comes with 2, 50, or 100 turns for varying sensitivity.
- Adjustable Vertical Stand – Allows proper leveling and alignment with Earth’s magnetic meridian.
- Low-Resistance Wiring – Minimizes energy loss and ensures accurate current measurement.
- Brass or Aluminum Fittings – Corrosion-resistant materials for durability.
- Dual Binding Posts – For easy connection with an external circuit or power source.
- Portable and Lightweight Design – Easy to transport and set up in laboratory environments.
- Educational Utility – Ideal for demonstrating the tangent law and studying the relation between current and magnetic field in physics experiments.
