What Is Self Inductance?

Are you curious to know what is self inductance? You have come to the right place as I am going to tell you everything about self inductance in a very simple explanation. Without further discussion let’s begin to know what is self inductance?

In the intricate world of electromagnetism, self-inductance emerges as a captivating phenomenon that governs the behavior of electrical circuits. This article endeavors to demystify the concept of self-inductance, exploring its intricacies, applications, and the magnetic dance it orchestrates in the realm of physics.

What Is Self Inductance?

Self-inductance is a fundamental property of an electrical circuit or a coil that describes its ability to induce an electromotive force (EMF) in itself when the current flowing through it changes. This phenomenon manifests as a magnetic field, creating a dynamic interplay between electric current and magnetic flux within the circuit or coil.

What Is Self-Inductance and Mutual Inductance:

Distinguishing between self-inductance and mutual inductance is pivotal. Self-inductance refers to the induction of EMF in a circuit or coil due to its own changing current, while mutual inductance involves the influence of one coil on another, inducing EMF in the second coil.

What Is Self-Inductance in Physics:

In physics, self-inductance is a manifestation of Faraday’s law of electromagnetic induction. This law states that a changing magnetic field within a coil induces an EMF in the coil itself, creating a dynamic relationship between magnetic flux and electrical current.

What Is Self-Inductance Class 12:

For students at the class 12 level, delving into the realm of self-inductance involves a comprehensive exploration of its principles and applications. The curriculum typically covers the mathematical formulations, derivations, and practical implications of self-inductance in electrical circuits.

What Is Self-Inductance Formula:

The self-inductance of a coil is quantified by the formula L= NΦ/I, where L is the self-inductance, N is the number of turns in the coil, Φ is the magnetic flux, and I is the current flowing through the coil. This formula elegantly captures the relationship between these parameters.

Self-Inductance Unit:

The unit of self-inductance is the Henry (H), named after the American scientist Joseph Henry. One Henry is equivalent to one volt-second per ampere, representing the amount of inductance that induces one volt of EMF when the current changes at a rate of one ampere per second.

Self-Inductance Derivation:

The derivation of the self-inductance formula involves applying Faraday’s law and considering the mutual inductance between turns in the coil. The detailed derivation showcases the intricate relationship between magnetic flux, current, and the number of turns in the coil.

Self-Inductance of Solenoid Formula:

For a solenoid, a common configuration in electrical circuits, the formula for self-inductance (L) is L= μN2A/l, where μ is the permeability of the material, N is the number of turns, A is the cross-sectional area, and l is the length of the solenoid.

Mutual Induction:

While self-inductance deals with the influence of a changing current on its own circuit, mutual induction explores the interaction between two separate coils. When the magnetic field of one coil affects the other, inducing EMF, mutual induction comes into play.

What Is Self-Inductance:

In essence, self-inductance is the inherent property of a coil or circuit to generate an electromotive force in response to changes in the electric current flowing through it. This magnetic dance between current and flux forms the backbone of inductance in electrical systems.


In conclusion, understanding self-inductance illuminates the intricate relationship between electric current and magnetic fields. From the foundational principles introduced in physics class to the advanced derivations explored at the class 12 level, self-inductance remains a captivating concept that shapes our understanding of electromagnetic phenomena. As we peer into the magnetic dance orchestrated by self-inductance, the elegance of its principles and applications becomes increasingly apparent, contributing to the rich tapestry of electromagnetism.


What Do You Mean By Self-Inductance?

Self-inductance is the property of the current-carrying coil that resists or opposes the change of current flowing through it. This occurs mainly due to the self-induced emf produced in the coil itself.

What Is Self-Inductance And S.I. Unit?

Self-inductance of a coil is numerically equal to the amount of magnetic flux linked with the coil when unit current flows through the coil. The S.I. unit of self inductance is henry (H) or weber per ampere. 1 H = 1 Wb/A.

What Is Self-Inductance And Mutual Inductance?

Mutual inductance is simply the generation of an induced EMF in a coil as a result of current flowing in an adjacent coil. In self-inductance, changes in the flow of current in a coil are opposed by the coil itself by inducing an EMF in the same coil, i.e., no other coil is involved.

What Is Inductance In Simple Words?

Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The electric current produces a magnetic field around the conductor. The magnetic field strength depends on the magnitude of the electric current, and follows any changes in the magnitude of the current.
