I am creating a model to see the effect of an object's relative permittivity and the attractive force that is generated by bipolar electrodes (applied voltage).
I am using an Electrostatics study. I have two electrodes (one is +150V, and the other is -150 V). Below the electrodes, I have a dielectric object (acrylic plastic), which relative permittivity I change.
In theory, the result should be a linear line that passes through the (0,0) point, and the force will increase linearly as the relative permittivity increases. That is not the case for my model.
You can see a screenshot of the plot below. Note: the y-axis shows a normalized version of the attractive force https://drive.google.com/file/d/1N_wZy_B5gjndK2k_3LCZCXRXUCW_20L1/view?usp=sharing
Can anybody please explain what is happening? Are the results correct? Thank you!
