Finding permability of free space from Magnetic Field vs. Current graph

[BrownPrincezz]

I graphed Magnetic Field (T) vs Current (A) and my slope was equal to 0.0012 which is off by 10^-3. Can someone suggest why this could be happening?

What data did you use to plot the graph?

What data did you use to plot the graph?

I used the Magnetic field data in Gauss (I did convert it) and Current in Amperes

There are a few possible reasons why your slope may be off by 10^-3. One possibility is that there may be experimental errors or uncertainties in your measurements of magnetic field and current. It is important to carefully calibrate and check your equipment to ensure accurate readings. Another possibility is that there may be external factors affecting your results, such as electromagnetic interference or magnetic fields from nearby objects. Additionally, the material and geometry of your setup can also affect the relationship between magnetic field and current, so it is important to consider these factors when analyzing your data. It may also be helpful to repeat the experiment multiple times and take an average of your results to minimize any potential errors. Overall, it is important to carefully consider all factors and sources of error when analyzing experimental data and to ensure proper experimental techniques are used to obtain accurate results.
