Not to worry, i got the answer. I was using the wrong equation.
For values of Magnetic Field inside the given radius the equation is
B = µIr / 2πa^2
B = (4π x 10^-7)(2.17)(0.01245) / 2π(0.0249^2)
B = 8.71e-6 T
In case anyone else had the same or similar problems.

The neutral neptunium atom has 93 electrons.
What is the magnitude of its electric field at a distance of 6.5x10-10 m from the nucleus?
Hint: The number of protons in a nucleus is equal to the number of electrons in the neutral atom.
q = 1.6e-19 * 93 =...
I'm assuming that the 3 and the 2 that you're using are the charges? Then why not add the Negative to the two? or is it irrelevant in this case
E3 = 3/(x)^2
E2 = 2/(x-d)^2
3.17 / x2 = 2.19 / (x - d)2
√(2.19 / 3.17) = (x - d) / x
√(2.19 / 3.17) = (1) - (d / x)
0.8311 = 1 - (d / x)...
