is not included in the simulations
The transient behavior when applying an AC magnetic field with frequency f is shown in Figure 7 and Figure 8.
The pSPICE simulation is compared with analytical calculations according to Equation (2.2) and
Equation (2.3) below. Again, a good fit is achieved using R = 4kΩ for the calculation.
