<math> H_{\phi}(r = 0.01m) = \frac{12.566A}{(2\pi)(0.01m)} = 200A/m </math>
Next, open the Data manager and plot the data file âSensor_1_X_HTotal.DATâ in EM.Grid. As you can see from the figure below, for 0 < r ≤ a = 2mm, the field varies linearly with the distance, while for r > a, it drops as 1/r.

Also plot the data file âSensor_1_X_HTotal.DATâ in EM.Grid and compare it to the previous graph of the single current case. Note how the magnetic fields of the two currents add up in the midway vertical plane and create a much higher field intensity on this plane.

Also plot the data file âSensor_1_X_HTotal.DATâ in EM.Grid and compare it to the previous graph of the case without the magnetic fixture. You can see that the magnetic field intensity at the center of the magnetic material (x = 0) has dropped down to 635A/m compared to the a much higher value of 1060A/m at the same spot in the previous case.

Also plot the data file âSensor_1_X_HTotal.DATâ in EM.Grid and compare it to the previous graph of the case the solid magnetic fixture. Note all the magnetic field discontinuities that occur at the air-material interfaces at x = -7mm, -2mm, 2mm, 8mm, 10mm and 17mm.
