Question about magnetic swing.

[Dude5.]

Hi again,
Sorry
Is it convenient to aks if someone knows for sure 
will the magnetic swing rotate as shown in the attached picture .
Thank you really.

There is good analogy of this setup :
Pipe with deflecting plate attached firmly together , where compressed air from pipe is blowing the deflecting plate :

Also another idea setup with flexible joints :

If the coil and metal plate are attached firmly together and can move only as a whole then there is no relative movement between the coil and plate. 

Eddy currents are induced in the plate only as a result of the changes in magnetic flux that attempts to penetrate that plate.  These variations of the magnetic flux cannot happen due to the nonexistent motion between the coil and the plate but they can happen due to varying electric current flowing through the coil. 

The force between the coil and the plate resulting from this alternating current is not always repulsive.  It is not repulsive when the current induced in the previous cycles has not decayed yet. This happens in low resistance and superconductive systems. 

Even if the current from the previous cycle has decayed, the repulsion force between the coil and the plate is symmetrical according to Newton's 3rd Law of motion.  This means that the force acting on the plate is equal in magnitude but opposite in direction to the force acting on the coil.  Because the coil and the plate are "attached firmly together" then these forces cancel and no net force is available to cause any kind of acceleration of the coil+plate assembly in accordance with Newton's 2nd Law of motion a=F/m. This is the same mechanism that prevents you from lifting yourself up by your bootstraps.

Also, the current induced in a shorted ideal coil (or plate) is proportional to the attempted change of magnetic flux (ΔΦ) that would penetrate this coil (or plate) if they were not shorted - the induced current does not depend on the change of magnetic flux density (ΔB) inside of a coil or any fixed current loop.
