The excel file named: Dataset for [Magnetic stimulation in the microscale: the development of a 6x6 array of micro-coils for stimulation of excitable cells in vitro] contains the raw data of the relevant figures in the manuscript.
Some further information regarding the excel sheets, each of which is named after the figure number, is given below: 

Figure 3: Field maps of magnetic flux density and induced potential produced by COMSOL Multiphysics. 

Figure 4: Figure 4c is obtained by taking the average of the two datasets given in sheet 4. 

Figure 5: The plots of figure 5 are obtained by further post-processing (average)of the 2 datasets on sheet 5. 
Inductance is further calculated from the known relation L=reactance/2πf=Z*sin(theta)/(2*pi*f) and quality factor Q=reactance/resistance=(Z*sin(theta))/(Z*cos(theta)).

Figure 6: Field maps (a, b) and line plot (c) obtained from COMSOL software. 

Figure 7: No dataset available as the figure is obtained by running the NEURON code. 
We use the model and NEURON code of Pashut et al.(reference [14] in the manuscript). 
The spatial part on the NEURON code in our case is extracted from COMSOL and is given in figure 6.
The temporal part is based on our RLC equivalent circuit, with the values of R, L, C as described in the manuscript.

Figure 8: Plots of dielectric permittivity and conductivity are created based on the 3 datasets presented on Sheet 8. The sheet explains the equations used to obtain relative permittivity and conductivity from the capacitance  (Cp) and conductance (Gp) measurements on a capacitor, filled with the unknown dielectric (the phantom gel). The bibliographic data of Gabriel et al. (reference [25] in the manuscript) is also included in this sheet, for the frequency range under study.

Figure 9: Obtained by the data presented on sheet 9. Vpp indicates the applied voltage to the micro-coils (peak-to-peak value).
