Mutual inductance
In the AIIMS entrance exam syllabus for physics, the topic of mutual inductance falls under the chapter of Electromagnetic Induction. Mutual inductance is an important concept in electromagnetism that describes the interaction between two coils of wire.
Mutual inductance occurs when the magnetic field produced by one coil of wire induces a voltage in the other coil. This phenomenon is based on Faraday’s law of electromagnetic induction. When the current flowing through one coil changes, it creates a changing magnetic field around it. This changing magnetic field induces an electromotive force (emf) in the neighboring coil, resulting in a current flow.
Key points to understand about mutual inductance:
- Definition: Mutual inductance (M) is a measure of the ability of one coil to induce a voltage in another coil. It depends on the physical properties of the coils, such as their size, shape, and relative position.
- Units: The unit of mutual inductance is the henry (H), named after Joseph Henry, a physicist who made significant contributions to the study of electromagnetism.
- Formula: The mutual inductance between two coils can be calculated using the formula:M = (N₂ * Φ₁) / I₁Where:
- M is the mutual inductance
- N₂ is the number of turns in the second coil
- Φ₁ is the magnetic flux through the first coil due to the current in it
- I₁ is the current flowing through the first coil
- Self-Inductance vs. Mutual Inductance: Self-inductance refers to the induction of voltage in a single coil due to its own changing current, while mutual inductance involves the induction of voltage in one coil due to the changing current in another coil.
- Applications: Mutual inductance has practical applications in various devices, such as transformers, where it is utilized to transfer electrical energy from one coil to another. It is also employed in circuits for impedance matching, inductors, and inductive sensors.
It is important to study the concept of mutual inductance thoroughly, as it forms the foundation for understanding more advanced topics in electromagnetism and electrical circuits.

Case Study on AIIMS-SYLLABUS Physics syllabus Mutual inductance
Transformers
Transformers are devices that utilize mutual inductance to efficiently transfer electrical energy between different circuits. They play a crucial role in the transmission and distribution of electricity across power grids.
Scenario: Imagine a power plant generating electricity at a high voltage. This electricity needs to be transmitted to households and businesses at a lower voltage for safe consumption. To achieve this, a transformer is used.
Application of Mutual Inductance:
- Step-Up Transformer: At the power plant, a step-up transformer is employed to increase the voltage of the generated electricity. The primary coil of the transformer is connected to the power plant’s high-voltage supply, while the secondary coil is connected to the transmission lines. The mutual inductance between the coils allows the transformer to efficiently transfer electrical energy from the primary to the secondary coil.
- Transmission: The electricity at the increased voltage is transmitted over long distances through power lines. This high voltage is necessary to minimize energy losses during transmission.
- Step-Down Transformer: Before reaching individual households and businesses, a step-down transformer is used to decrease the voltage to a safe and usable level. The primary coil of the step-down transformer is connected to the transmission lines, while the secondary coil is connected to the distribution lines that supply electricity to consumers.
Benefits and Significance: Mutual inductance enables the efficient transmission of electricity over long distances. By increasing the voltage at the power plant and stepping it down at the destination, the losses due to resistance in the power lines are minimized, allowing for more efficient power delivery.
Moreover, the use of transformers ensures that the electricity supplied to consumers is at a safe voltage level suitable for various appliances and devices. This protects electrical equipment from damage and reduces the risk of electric shock.
In conclusion, transformers serve as a practical application of mutual inductance, allowing for efficient transmission and distribution of electricity across power grids. They play a vital role in the electrical infrastructure and contribute to the reliable and safe supply of electricity to consumers.
