How is the mutual inductance of a pair of coil affected when (a) Separ...
Explain your answer in each case. (i) When separation between the coils is increased, magnetic flux linked with secondary coil decreases. Therefore, mutual inductance (M) of pair of coils decreases. The total number of magnetic lines of force crossing any surface in the magnetic field is termed as magnetic flux.

Effect of different factors on mutual inductance:

1. Separation between the coils:
When the separation between the coils is increased, the mutual inductance decreases. This is because the magnetic field produced by one coil has less influence on the other coil when they are farther apart. The flux linkage between the coils is reduced, leading to a decrease in mutual inductance.

2. Number of turns in each coil:
Increasing the number of turns in each coil increases the mutual inductance. This is because more turns in a coil result in a stronger magnetic field and hence a higher mutual inductance. The flux linkage between the coils increases with the number of turns, leading to a higher mutual inductance.

3. Introduction of a thin iron sheet:
When a thin iron sheet is placed between the coils, the mutual inductance increases significantly. This is because iron is a ferromagnetic material that enhances the magnetic field produced by the coils. The iron sheet acts as a magnetic conductor, concentrating the magnetic field lines and increasing the flux linkage between the coils. As a result, the mutual inductance is greatly enhanced.
In conclusion, the mutual inductance of a pair of coils is affected by factors such as the separation between the coils, the number of turns in each coil, and the introduction of a magnetic material like an iron sheet. Adjusting these factors can help in controlling and optimizing the mutual inductance between coils.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same: TOROIDA toroid is a coil of insulated or enamelled wire wound on a donut-shaped form made of powdered iron. A toroid is used as an inductor in electronic circuits, especially at low frequencies where comparatively large inductances are necessary. A toroid has more inductance , for a given number of turns, than a solenoid with a core of the same material and similar size. This makes it possible to construct high-inductance coils of reasonable physical size and mass. Toroidal coils of a given inductance can carry more current than solenoidal coils of similar size, because larger-diameter wires can be used, and the total amount of wire is less, reducing the resistance . In a toroid, all the magnetic flux is contained in the core material. This is because the core has no ends from which flux might leak off. The confinement of the flux prevents external magnetic fields from affecting the behaviour of the toroid, and also prevents the magnetic field in the toroid from affecting other components in a circuit. Standard toroidal transformers typically offer a 95% efficiency, while standard laminated transformers typically offer less than a 90% rating. One of the most important differences between a toroidal transformer and a traditional laminated transformer is the absence of gaps. The leakage flux through the gaps contributes to the stray losses in the form of eddy currents (which is also expelled in the form of heat). A toroidal core doesn’t have an air gap. The core is tightly wound . The result is a stable, predictable toroidal core, free from discontinuities and holes. Audible vibration or hum in transformers is caused by vibration of the windings and core layers from the forces between the coil turns and core laminations. The toroidal transformer’s construction helps quiet this noise. In audio, or signal transmitting applications, unwarranted noise will affect sound quality, so a transformer with low audible vibration is ideal. For this reason, many sound system engineers prefer to use a toroidal transformer instead of a traditional laminated transformer.Why inductance of solenoid is more than the inductance of a solenoid having same number of turns, core of same material and similar size?
