Q. How does the concept of displacement current associated in the behavior of electric and magnetic fields?
Submit Your Answer
According to Faraday’s law of electromagnetic induction, a time-varying magnetic field induces an emf, According to Maxwell, an electric field sets up a current and hence a magnetic field. Such a current is called displacement current. It follows that a time-varying electric field produces a magnetic field and vice-versa. Hence, the behavior of the electric and magnetic field is symmetric.
