Tangent Galvanometer Manufacturer,Supplier and Exporter in India
Product Code : SCL-M-11272
The apparatus combines a circular current-carrying coil with a compass box positioned near its centre. When current passes through the coil, the resulting magnetic field interacts with the horizontal component of Earth’s magnetic field and turns the magnetic needle through a measurable angle.
Students can use the observed deflection to verify the tangent law or calculate current when the coil constant and local magnetic-field value are known. The exact coil diameter, number of turns, terminal configuration, scale graduation and construction materials must be confirmed for the supplied model.
Key Features
Demonstrates the tangent law: Relates compass deflection to the ratio of two mutually perpendicular magnetic fields.
Shows the magnetic effect of current: Makes the field produced by a current-carrying circular coil measurable through needle movement.
Supports current determination: Allows current to be calculated from coil parameters, magnetic-field data and deflection.
Central compass arrangement: Positions the magnetic needle near the field region used for the experiment.
Multiple connection terminals: May support different coil-turn selections, subject to the confirmed model configuration.
Adjustable laboratory setup: Enables alignment of the coil and compass with the magnetic meridian.
Suitable for practical instruction: Supports demonstrations, student measurements and observation-based calculations.

How to Use the Tangent Galvanometer
Place the galvanometer on a stable bench away from magnets, steel objects and current-carrying equipment not used in the experiment.
Level the apparatus and rotate it until the coil lies in the magnetic meridian.
Confirm that the compass needle reads zero when no current is flowing.
Connect the selected coil terminals in series with a suitable DC source, key, rheostat and ammeter.
Close the circuit and adjust the current gradually until a clear, stable needle deflection is obtained.
Record the current and deflection angle, then reverse the current and repeat the observation to reduce directional error.
Calculate the required result using the approved tangent-galvanometer formula and the confirmed coil parameters.
Safety note: Use current limiting, avoid excessive coil heating and switch off the circuit before changing terminals. Keep magnets, mobile devices and ferromagnetic objects away from the compass.
Care and Maintenance
Store the apparatus in a dry cabinet and protect the compass from shock.
Clean the scale cover and frame with a soft, dry cloth.
Inspect terminals and coil connections before each practical session.
Do not place magnets or heavy metal objects near the compass during storage.

Frequently Asked Questions
What is a Tangent Galvanometer used for?
It is used to verify the tangent law, study the magnetic field of a circular coil and determine current from the deflection of a compass needle.
How does a Tangent Galvanometer work?
Current in the circular coil creates a magnetic field perpendicular to Earth’s horizontal magnetic field. The compass needle aligns with the resultant field and shows an angular deflection.
What is the tangent law?
When two uniform magnetic fields act at right angles, the tangent of the needle’s deflection angle equals the ratio of their magnetic-field strengths.
Why must the coil be aligned with the magnetic meridian?
Correct alignment makes the coil’s magnetic field perpendicular to the horizontal component of Earth’s field, which is required for the tangent-law calculation.
Can the apparatus measure current directly?
It does not provide a conventional direct meter reading. Current is calculated from the measured angle, coil geometry, number of turns and the relevant magnetic-field value.
Is the Tangent Galvanometer suitable for school laboratories?
Yes. It is suitable for supervised senior-secondary, college and teacher-training experiments involving electricity and magnetism.
