Inside a flat capacitor, parallel to its plates, a conducting plate moves at a speed v, the thickness of which is equal to half the distance between the plates of the capacitor. A voltage V is maintained on the capacitor plates, and the distance between them is h.
a. What is the induction of the magnetic field inside the conductor? between the moving conductor and the capacitor plates?
b. How will the induction of the magnetic field in the plate change if the conductor is replaced by a dielectric with a permittivity ϵ?
