When the coil is excited, an electromagnetic force is induced causing the plunger to translate. This example treats this kind of problems. A motion study is setup using SW motion, then the Magnetostatic Study of EMS is couple to it. The EMS solver and the motion solver will be communicating at each step to exchange information about the force and location of the plunger. EMS will calculate the force at the initial position then the force value is passed to the SW Motion ; which in turn will take the force value apply it to the plunger, calculate the new position and then feed it back to EMS. The EMS solver will recalculate the force based on the new location. Both solvers will keep going back and forth until all the steps are covered
