Distance away to create the same magnetic field strength?

[conov3]

1. Homework Statement

At what distance (in m) from a very thin, straight wire carrying a 38 A current would the magnetic field strength be the same as a refrigerator magnet of 4.35 x 10-3 T?

2. Homework Equations

B=(μo/2pi)*(I/d)
where μo=4pi*10^-7

3. The Attempt at a Solution

4.35e-3(d)=2.0e-7*(38)
d=.0017m
It says this is wrong? so I must have done something wrong.. any help would be appreciated!
Thanks for your time!

that's what I got too, is this an online homework? Did you try 0.00169? Sometimes they can be annoying with sig figs.

Yes, I just tried that.. and it didn't say it was correct. It usually will give me the answer if it is that close but it says that is the wrong answer.
