Alright, my teacher gave us a review sheet of problems for the test tomorrow, supposedly all the concepts will be covered on the test, and I've got NO CLUE where to even start on this problem. It supposedly has something to do with section 30.7 in Serway/Beichner's physics text, titled "Displacement Current And The General Form Of Ampere's Law", but I can't find anything in there or elsewhere that helps me understand this.
----------------------------------------------------
A .4A current is charging a capacitor that has circular plates 13cm in radius.
(a) If the plate separation is 4.00 mm, what is the time rate of increase of electric field between the plates?
(b) What is the magnitude of the magnetic field between the plates 5.00 cm from the center?
----------------------------------------------------
I can't find any equations relating capicitor charging with magnetic fields, or vice versa... help? Please? I'm on my knees here!
