Earth's magnetic field in Brisbane

[ausdreamer]

Homework Statement

Calculate Earth's magnetic field in Brisbane. (This was for a lab report)

Homework Equations

B = (8.991E-3)*I*N/R = 0.6034*I (I = current going through helmholtz coils)

The Attempt at a Solution

I've calculated a value of 0.278 Gauss for Earth's magnetic field. Surprisingly, however, I haven't found values anywhere to check my calculation and hoped someone could verify my value?

Sorry for posting a badly written question but this isn't really an assignment question but more to verify my lab results aren't too far off.

Would 0.286 Gauss be the entire local field strength, or just the local horizontal component?

You can find local field strengths http://www.ngdc.noaa.gov/geomagmodels/IGRFWMM.jsp" .

The horizontal field. My value lies within their given range, thank you gneill :)
