A parallel-plate capacitor with circular plates of radius R = 16 mm and gap width d =
Question:
A parallel-plate capacitor with circular plates of radius R = 16 mm and gap width d = 5.0 mm has a uniform electric field between the plates. Starting at time t = 0, the potential difference between the two plates is V = (100 V) e-t/τ where the time constant r = 12ms. At radial distance r = 0.80R from the central axis, what is the magnetic field magnitude
(a) As a function of time for t > 0 and
(b) At time t = 3τ?

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
