Lorentz Forces in Switches and Contacts - Application Brief

An area of concern for most electrical engineers who work with disconnectors and contacts is determining the electromagnetic force that sometimes causes them to open undesirably. ANSYS Maxwell software helps in calculating this force, allowing engineers to design switches that withstand the force. Further, parametric study can be conducted to evaluate the influence of design variables, such as thickness of a switch or current through contact on the electromagnetic force.
