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

  1. Mar 28, 2012 #1
    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?

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