An Excellent Tool For Visualizing Electric Field And Equipotential Lines

You can see invisible electric field - if you use "Electric Field". It is an excellent tool forvisualizing electric field and equipotential lines. Visibility of field line and potential surface depends on their magnitude. You can put unlimited number of charges in the field. Also, it can simulate electric field of charged condenser, charged wire and charged dielectric objects. Download Electric Field for Free here. (International)
