Tangent Galvanometer

Product Code : SCL-EE-12412

Quick Answer: The Tangent Galvanometer is a physics instrument for verifying the tangent law, showing how current in a circular coil produces a magnetic field that deflects a magnetic needle.

Last updated: October 2026

Key Features

Circular current-carrying coil with a magnetic needle
Demonstrates and verifies the tangent law
Coil plane is aligned with the magnetic meridian before use
Used with a low-voltage DC supply, rheostat and ammeter

About This Product

The instrument is turned so that the coil plane lies in the magnetic meridian, then connected in series with a DC source, rheostat and ammeter. Students raise the current gradually, record the needle deflection for several current values within the safe range and use the readings to verify the tangent law. It supports practicals on electromagnetism and the earth’s magnetic field.

Frequently Asked Questions

Q1. What is recorded during the experiment?
