Question

Two coils A and B are placed close to each other. If the current in the coil A is changed, will some current be induced in the coil B? Give reason.

Answer 1

Explanation:

Two circular coils A and B are placed close to each other. When the current in coil A is changed, the magnetic field associated with it also changes. As a result, the magnetic field around coil B also changes. This change in magnetic field lines around coil B induces an electric current in it. This is called electromagnetic induction.

Answer 2

Answer:

• When the two coils ‘A and B’ are placed close to one other and if the ‘current in the coil A’ is changed, and some amount of current has been induced in coil, and there is some change in the induced magnetic field.
• This leads to a ‘magnetic field being created’ around coil B which in turn will induce some current in coil B.
• This is working on the ‘principle of electromagnetic induction’.
• The “process of producing induced current or electromotive force or voltage due to a change in magnetic field” is called as electromagnetic induction.
