A capacitor is hooked up to a resistor and an AC voltage source as shown in the figure.The output of the source is given by V(t)= V₀ sin ωt.The plates of the capacitor are disks of radius R.Point P is directly between the two plates,equidistant from them and a distance R/2 from the center axis.At point P A)there is no magnetic field because there is no charge moving between the plates. B)there is a constant magnetic field. C)there is a time-varying magnetic field.

Question

Quizplus · Accepted Answer

When there is a time-varying voltage across the capacitor, a time-varying electric field is generated between the plates. This changing electric field gives rise to a time-varying magnetic field according to Faraday's Law of Induction. Therefore, there is a time-varying magnetic field present at point P.
