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

 

Answer

ncert-question-14---answer---chapter-13-class-10-magnetic-field---teachoo.png

As the current flows in coil A, a magnetic field is generated around it.

As the coil B is situated near coil A, it also experiences the magnetic field.

 

As the current in coil A changes, the magnetic field associated with it also changes.

Hence, the magnetic field around coil B also changes.

 

Due to change in magnetic field around the coil B, a current is induced in coil B.
