For a magnetic fields lab I am asked to graph the data and from there, use the slope to find a certain value.
For one of them, I am asked to plot the current (x) vs the magnetic field (y).
The slope is supposed to give me a value, I have the slope, no clue what the value would represent. After some research I found that people are saying it represents the loops?
No clue what that is.
Anyway I also have to plot the distance (1/r) (x) vs the magnetic field strength (y) and the slope is supposed to be the permeability of a vacuum. I get 2E-7. Using 4piE-7, that's a deviation of 85%. I do have a feeling something is not right here.
Units for 1/r, are 1/m and units for magnetic field are T, while units for current are A.
Relevant equations:
B=(µ0I)/2πr
B=(µ0NI)/2R
This is no homework question, in fact I don't need a numerical answer. I just need to know if I'm on the right track.
Thanks.
