Question 14:
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.
Answer:
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.
