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.

Hi,
Im really helpless on this, could anyone please check the model? any kind of comment is worthy and also I could provide more detailed information about my objective from this model, if needed.
Thanks
