In the previous part of our Electromagnetic Device series, we showed you how to model a linear electromagnetic plunger attached to a spring and damper and compute the position, velocity, and electromagnetic forces. Here, we will demonstrate an actuator that includes a blocker/stopper to restrict linear motion. We will also discuss how to model the contact and release of this actuator using the Events, Magnetic Fields, Moving Mesh, and Global ODEs and DAEs interfaces.
