Hey guys, I trying to work out this formula for work. We have a magnetic solenoid that is suspended a certain distance from a sensor tool. This sensor has 3 magnetometers that measure the field strength in Bx,By,Bz directions. The magnetic solenoid is run with a constant current of 0.75A. We have software that will take these values, along with the Ax,Ay,Az, Inclination and Azimuth readings and tell us the distance in N/S and E/W. eg: 10m N, 5m W. I need to work out how this is calculated and was hoping someone here could be of assistance. Cheers.
