## Homework Statement

A 1400 nF capacitor with circular parallel plates 1.0 cm in diameter is accumulating charge at the rate of 25.0 mC/s at some instant in time. What will be the magnitude of the induced magnetic field 9.0 cm radially outward from the center of the plates?
T
What will be the magnitude of the field after the capacitor is fully charged?
T

## Homework Equations

Obviously i'm a little confused, but I believe the general equation is B=mevE where B is magnetic field, e is c^2/Nxm^2, m is Nxs^2/C^2...on second, thought, i'm very confused.
another possibility is B=(mu) initial x I/ 2 pi r

## The Attempt at a Solution

1400x25=35000x(1/9)=3888.89T
