Book Free DemoTwo 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.
The current if changed in coil A. Some current in coil B.
Whenever the electric current through coil–A is changing (starting or stopping), the is in coil-B.
Coil-A has known as the , and coil-B has known as the . As the current in the first coil varies, then the corresponding also changes. Thus the lines around the secondary coil (coil -B) also change.
Hence the change in associated with the secondary coil is the cause of induced electric current in it. This is called .
