Converting magnetic field strength into a vectorial distance.

Click For Summary

Discussion Overview

The discussion revolves around the calculation of distance from magnetic field strength measurements taken by a sensor tool equipped with magnetometers. The context involves a magnetic solenoid operating with a constant current and the use of additional readings such as inclination and azimuth to determine positional information in a North/South and East/West format.

Discussion Character

  • Exploratory, Homework-related

Main Points Raised

  • One participant seeks assistance in understanding how to derive a formula for calculating distance based on magnetic field strength measurements from a solenoid and a sensor tool.
  • The participant mentions specific parameters such as the constant current of 0.75A and the three-dimensional magnetic field components (Bx, By, Bz) measured by the sensor.
  • Another participant suggests that including an attempt at a solution and relevant equations may increase the likelihood of receiving helpful responses.
  • There is a sense of frustration expressed by the original poster regarding the lack of responses and assistance from the forum.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as the original poster expresses dissatisfaction with the lack of helpful responses, while another participant emphasizes the importance of providing an attempt at a solution.

Contextual Notes

The discussion lacks specific equations or methodologies that could clarify the relationship between magnetic field strength and distance calculation. There are also missing assumptions regarding the sensor's calibration and the environmental conditions affecting the measurements.

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.

anyone? maybe even just rough idea. I been trawling through the maths for 2 days now n can't seem to get anywhere.
 
hmm, well that's not very helpful is it. :\
 
The forum is usually pretty helpful, but you should include a attempt at your solution and relevant equations also. You'll be more likely to get a response.
