Mutual Inductance Determination Using Ballistic Galvanometer (Absolute Method)
Objective
To determine the mutual inductance between two coils using the Ballistic Galvanometer Absolute Method. The experiment demonstrates the principles of electromagnetic induction and enables the measurement of mutual inductance by observing the charge induced in a secondary coil when the current in the primary coil is varied.
Description
This experimental setup is designed to study the phenomenon of mutual induction between two closely coupled coils. When the current flowing through the primary coil changes, a varying magnetic flux is produced, which induces an electromotive force (EMF) in the secondary coil. The resulting transient current is measured using a highly sensitive ballistic galvanometer.
By analyzing the galvanometer deflection and the circuit parameters, the mutual inductance of the coil pair can be determined accurately. The experiment provides valuable insight into electromagnetic induction, magnetic coupling, transient currents, and energy transfer between coils.
The apparatus is ideal for undergraduate and postgraduate physics laboratories and serves as an important tool for understanding the practical applications of Faraday’s laws of electromagnetic induction.
