I thought it was "electro-static" field within the capacitor plates........is this a trick question?

anonymous · Answer

i haven't even learned that term yet so not a trick question.

i used Bpir^2=u_0*I... oh i think i use distance for r? i used radius of plates nd got the wrong answer

radar · Answer

same as electric field........  I can see electromagnetic field circling the conductor attached to each electrode of the capacitor,  what kind pattern would exist for an electromagnetic field within the dielectric (air in this case) of the capacitor?  Is this a physics or an electrical engineering question?

anonymous · Answer

it's physics, accidentally posted it here

anonymous · Answer

since it's not stated otherwise, it seems like uniform fields

Interesting, I have retired from the electronics field, and thankfully have not run into that question.  Good luck, there are some physics savvy people here, JamesJ being one of them.
