The Solution of Static-Shielding in Electrostatic Field Based on Ansoft

Static-shielding is an important knowledge point in the course of Electromagnetic Field and Electromagnetic Wave,An ordinary sphere shielding is an example based on software of Ansoft engineering electromagnetic field finite element analysis,electric field lines will be changed in the event of metal cavum grounding or not.At the same time electric field lines will be changed along a certain line.Results show all closed cavum being grounded is needed in order to achieve all shielding.The teaching and measures can increase the students' sensibility cognition on the electromagnetic field theory.
