The relationship of current in coil-2 to its emf is described by Mutual Inductance.
Mutual inductance is a phenomenon that occurs when two coils are placed near each other and the changing current in one coil induces an electromotive force (emf) in the other coil. It is a measure of the amount of mutual influence between the two coils.
When the current in coil-1 changes with time, it produces a changing magnetic field around it. This changing magnetic field induces an emf in coil-1 itself, which is known as self-inductance. However, due to the proximity of coil-2, the changing magnetic field also induces an emf in coil-2.
The induced emf in coil-2 depends on the rate of change of current in coil-1 and the mutual inductance between the two coils. The mutual inductance is a property of the two coils and is determined by factors such as the number of turns in each coil, the geometry of the coils, and the distance between them.
The current in coil-2 is directly related to the induced emf in coil-2. If the changing current in coil-1 produces a larger induced emf in coil-2, the current in coil-2 will also be larger. Similarly, if the changing current in coil-1 produces a smaller induced emf in coil-2, the current in coil-2 will be smaller.
Therefore, the relationship between the current in coil-2 and its induced emf is described by mutual inductance. Mutual inductance plays a crucial role in various applications, such as transformers, inductors, and electromagnetic devices. It allows for the transfer of energy and signals between different coils without direct electrical contact, enabling efficient and versatile electrical systems.
Explanation:
Mutual Inductance:
Mutual inductance is a phenomenon that occurs when two coils are placed near each other and the changing current in one coil induces an electromotive force (emf) in the other coil. It is a measure of the amount of mutual influence between the two coils.
Coil-1:
When the current in coil-1 changes with time, it produces a changing magnetic field around it. This changing magnetic field induces an emf in coil-1 itself, which is known as self-inductance. However, due to the proximity of coil-2, the changing magnetic field also induces an emf in coil-2.
Coil-2:
The induced emf in coil-2 depends on the rate of change of current in coil-1 and the mutual inductance between the two coils. The mutual inductance is a property of the two coils and is determined by factors such as the number of turns in each coil, the geometry of the coils, and the distance between them.
Current in Coil-2:
The current in coil-2 is directly related to the induced emf in coil-2. If the changing current in coil-1 produces a larger induced emf in coil-2, the current in coil-2 will also be larger. Similarly, if the changing current in coil-1 produces a smaller induced emf in coil-2, the current in coil-2 will be smaller.
Conclusion:
Therefore, the relationship between the current in coil-2 and its induced emf is described by mutual inductance. Mutual inductance plays a crucial role in various applications, such as transformers, inductors, and electromagnetic devices. It allows for the transfer of energy and signals between different coils without direct electrical contact, enabling efficient and versatile electrical systems.
