problem:
A capacitor has circle plates with radius R. the plates are at a distance h. between the plates there is a tension V. Find B, magnetic induction, at a distance r from the symmetry axis of the capacitor. See diagram attached.
what I did:
I know it has to be studied in two different cases:
1. r<<R
2. r>>R
I know...
(1)[tex]V=\int E dl=Eh \longrightarrow E=\frac{V(t)}{h}[/tex]
(2)[tex]\oint E dl=-\frac{d\phi(B)}{dt} [/tex]
But then how to go on?
Please please please help...!
