Question

define Henry and mutual induction with the help of diagram​

Answer 1

Answer:

Mutual induction is defined as the property of the coils that enables it to oppose the changes in the current in another coil. With a change in the current of one coil, the flow changes too thus inducing EMF in the other coil. This phenomenon is known as mutual induction. The circuit part that represents inductance is known as an inductor and the term inductance was found by Oliver Heaviside in the year 1886.

We can explain this with the help of an example. Consider the following diagram.

Mutual Induction

With a smooth current in one coil, as given in the diagram, a magnetic field is formed in the other coil. That magnetic field remains unchanged and hence, according to Faraday’s law, it will not lead to any voltage creation in the secondary coil. Now, if we open the switch so as to stop the current, the magnetic field will change in the coil placed on the right-hand side, thus inducing a voltage. The coil does not support changes and hence the induced voltage will promote a flow of current in the secondary coil trying to maintain the already existing magnetic field. The fact, however, remains that the induced field will always repel the change. On interrupting the current, the switch is closed so as to allow the current to flow again. This will lead to an induced current, though flowing in the opposite direction to oppose the change in the field. This consistent formation of opposing voltages in the field is the fundamental principle in transformers and can be called mutual inductance.

Mutual Inductance formula:

em = M (dI1 / dt)

or M = em/ (dI1 / dt)
