1. The problem statement, all variables and given/known data Displacement current arises due to a)changing electric field b)changing magnetic field c)both 2. Relevant equations 3. The attempt at a solution I think the answer should be c) because we already know that changing electric field is responsible for displacement current. But if the magnetic field is also time-dependent then it will induce an electric field according to Faraday's law. So, the induced electric field will also contribute to the displacement current. However, the correct answer is a).
