Hey everybody! Let's say we have an infinite metal plate, and we apply voltage between two points, thus creating a potential. On this plate, we take a cutter and create a finite gap (filled with air), somewhere between the electrodes that apply the voltage. Simulations in ANSYS show that the current vectors curve around the gap much like a liquid does around an obstacle. Does anyone know the physical effect that causes this? I would speculate that it is a surplus of electrons creating a small charge distribution around the insulator, but I can't see how it fits into Maxwell's equations. Any pointers would be great!
