Differences Between Self-Inductance and Mutual Inductance
Although both self-inductance and mutual inductance involve the generation of voltages as a result of changes in magnetic fields, they differ in several primary aspects:
|
Differences |
Self-Inductance |
Mutual Inductance |
|---|---|---|
|
Circuits |
occurs within a single circuit |
occurs within minimum two circuits |
|
Cause of induced EMF |
Change in current in the same coil |
current change in one coil affecting another |
|
Effect of induced EMF |
Opposes change in current |
Can be in the same or opposite direction depending on orientation |
|
Applications |
Inductors, filters |
Transformers, coupled inductors |
Single Vs Multiple Circuits
Self induction occurs within a single circuit or conductor while mutual inductance is about the linking between two or more entirely different circuits or conductors.
The Magnetism Source
In self-inductance, the magnetic field inducing voltage is produced by similar stream of current that has been flowing via the circuit or conductor. On the other hand, mutual induction results into an induced voltage caused by a distinct circuit else wire.
Energy Transfer
Unlike self-induction which does not provide any energy flow between circuits since it opposes change of current within itself via an induced voltage. But, this process allows energy from one circuit to another through sharing magnetic field existent in mutual inductance.

Differences between Self-Inductance and Mutual Inductance
Self-inductance and mutual inductance are both the ways in which electric currents and magnetic fields interact. both self inductance and mutual inductance are measured in henrys (H). In this article, we will look into their differences along with advantages, disadvantages, applications, etc.
Filters are frequently utilized for self-inductance and chokes also help store energy whereas transformers are required for mutual inductions due to their significance along with coupled inductors and wireless power transfer systems.
