…amples basic_inductor_electrostatic and basic_transformer_electrostatic are examples for electrostatic simulation. The Validation of simulation is existed also with FEMM using femm_reference_electrostatic.
…ll bobbins dimensions are defined
…insulation is added but it is now air material. Also the user can choose the air insulation between the turns in every layer in every winding.
…tions for integrated transformer
…atic_solver, needed to be modified

can you make the example more clear?
i think it is maybe
[[V_winding_1_turn_1, V_winding_1_turn_2], [V_winding_2_turn_1, V_winding_2_turn_2]]
?

use another word for kapton

the new added basic examples regarding the electrostatic simulation should also be executed in test_femmt.py to make sure, that the examples are working

done u can check the test file

From where does this "Infinity" occur?
