Assertion (A) : Time rate change in magnetic field produces electric field.
Reason (R) : Time rate change in electric field produces magnetic field.
Answer & explanation
Correct answer: option 2
A time varying electric field produces a magnetic field. This phenomenon is called Ampere-Maxwell equation.
Ampere's law in addition of Maxwell's states that magnetic field can be generated in two ways either by electric current or by changing the electric field.
The displacement current is given by Maxwell's. A time-varying magnetic field causes flux to fluctuate, resulting in an electric field.
