Two circular coils A and B are placed closed to each other. If the current in the coil A is changed, will same current be induced in the coil B? Give reason. |
| Answer» Solution :Two circular coil, A and B are placed close to each other when the current in coil A is changed, the magenetic field ASSOCIATED with it ALSO changes. As a result the magentic 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. | |
