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.

उत्तर १
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.

उत्तर २
Yes, some current will be induced in coil B because with the change in current in coil A, the magnetic field produced by it will change. This change in the value of magnetic field will induce current in coil B.
