Energy is NEVER irrelevant.
So we can use potential energy with attraction forces to move an object without exhaust.
When the belt magnets are forced into the repelling magnetic fields of the body magnets they will repel with equal and opposite force so the spacecraft will not move. As the belt magnets pass across the hull magnets they will receive a push from the hull magnets and vice versa.
So will the body be pushed back after each interaction
and secondly if we switch the motors off just as the belt magnets pass across the body magnets what will happen?
With the electromagnets we can switch the motors off as the magnets approach one another so causing them to transfer momentum through collision.

So we can use potential energy with attraction forces to move an object without exhaust.No. You have been told this repeatedly, and not acknowledged it. Do you know what the phrase "center of mass will not move" means? Specifically are you even familiar with the concept of "center of mass"?When the belt magnets are forced into the repelling magnetic fields of the body magnets they will repel with equal and opposite force so the spacecraft will not move. As the belt magnets pass across the hull magnets they will receive a push from the hull magnets and vice versa.You are referring to 3 sets of magnets here, "body" "hull" and "belt" but you only described placing 2 sets, the "hull" and the "belt" for now I am going to assume you that body and hull refer to the same thing, if that is not true, you are going to need to provide a new description that isn't incomplete. (a diagram would help)So will the body be pushed back after each interactionNo, because the forces are equal and opposite. The magnets on the belt which is taut between the wheels transfer the force applied to them to the wheels, which are rigidly connected to the motors which are rigidly connect to the hull, so the hull has equal and opposite forces applied to it and does not move.and secondly if we switch the motors off just as the belt magnets pass across the body magnets what will happen?Nothing. The equal and opposite forces would be constant instead of periodic, still nothing would move.With the electromagnets we can switch the motors off as the magnets approach one another so causing them to transfer momentum through collision.How would anything collide? You have not described anything with the freedom of movement to collide with something else.
Your entire setup is a Rube Goldberg machine with no apparent purpose other than trying to hide your misunderstanding of physics by making the setup complicated. Rather than changing topic yet again why don't you go back to the situation of just 2 magnets, one attached to you, and one that you push away and then allow it to be attracted back to you. I provided a detailed description of the forces in that situation, and you have not indicated if you understood that post at all.

Sure you can... If the potential energy is with respect to something outside of your device like the gravitational attraction of a planet such as when doing an Oberth maneuver but not internally to your device.

I am in space and am holding the ends of a spring. I PULL on the spring and stretch the spring. The spring applies an equal and opposite force on each hand so I do not move. I let go of the spring. Please, please, tell me and everyone reading this thread that the spring when it is contracting does NOT apply a force on the hand that is holding the one end of the spring.

The force the spring applies to both hands when stretched disappears the instant one hand let's go. Any residual effects that happen due to potential energy stored in the spring and the muscles of both arms won't end up moving the center of mass of the system.

I asked will the contracting spring apply a force to the one hand?
Are you saying that when the motor on the device is switched off the rotor arms do not collide with the body magnet?
The word is PULL. Why do you keep misquoting?

The force exists before the spring is let go but not after. So, I believe no, the spring doesn't apply a force to the hand that remains holding it.
Then it's a two body problem, one hand and the spring and the hand that let go.
One hand and the spring will move one way < > the other hand will move the other way
But the centre of mass of the combined system (both hands and the spring) will stay in the same place.
Live empirically! No need to ask people what they think about this. Build a model of the system you are thinking of. It might be suspended above an air table or floating on still water. Use a small radio-controlled actuator to release the end of the spring. Run the experiment and report back to us.
If you are not afraid of simple maths, try reading this, Collisions
Are you saying that when the motor on the device is switched off the rotor arms do not collide with the body magnet?What rotor arms? you didn't describe any rotor arms in your post, and if you are somehow referring to the device that you previously were discussing, you did not state that. Even if that is what you were discussing, there are no collisions between the body and the arms in your device.The word is PULL. Why do you keep misquoting?I am not misquoting, because I am not quoting you. I am independently describing things using the correct words.
You keep saying that you are moving something away from you by pulling it, but as I stated in a previous post, by definition applying a force to move something away from you means pushing it. Pulling it would move it towards you.

You also completely ignored the questions I asked in the previous post such as: Do you know what "center of mass" means?
If I can offer some advice, if you find yourself stabbed in the stomach do not attempt to pull the knife from your body.
And yes I do know what center of mass means,
What do you know about about second law?
