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

__Given:__

Two circular coils **A** and **B** are placed close to each other.

__Action:__

The current in coil A is changed.

__To find:__

It is to be observed whether current is induced in coil **B** when the current flow in coil **A** or not.

__Observation:__

When two circular coils **A** and **B** are placed close to each other. If the current in coil A is changed then the magnetic field of coil A will also get changed. So, magnetic field lines associated with coil B will also get changed, so an induced current will be set up in coil B due to emf$(electromotive\ force)$. On observing it is found that the needle of the galvanometer shows some deflection. This deflection indicates that a current is induced in coil B also when the current in the coil is changed if both coils A and B are placed close to each other.
