Problems with moving mesh application

Hello,
I'm trying to model a multi turn coil with a fixed exciting current scanning over a conductor. in order to define a displacement for the coil, I took following steps:
1- I defined a coil unified with air domain and a conductor , an identity pair boundary generated from assembly between conductor and air domain.
2- continuity boundary condition is used for the interface (Identity pair boundary) .
3- two job steps: frequency domain for field of the coil and time dependent forcoil displacement were defined .
I tried to find moving mesh 3D examples but they were all built for 2d axisymmetric geometries or rotational systems. Since I want to introduce a discontinuity in the conductor later, I wont be able to set up the model by 2d axisymmetric. Assume I replaced the conductor with air without changing the identity pair, In this case which boundary condition gives me a perfectly continius field through the boundary. Or simply which boundary condition wont disturbe the field distribution of the coil just like that all domains are unite.
In fact I dont know if there is any other way to assign the movement to coil instead of spliting the geometry and generating identity pairs.
I attached my model and I know it has severe issues, I'll be grateful if anyone could help.
