The device is in orbit.
so it does not experience any friction outside
the entire thing.

We will start with a tube 10 ft long placed inside the device.
In the tube we place a iron cored piston that has friction
but slides with a magnetic pulse applied to the outside
and will not stop instantly but will slide and finally slow down
after about seconds of motion.
We set the piston at 2 inches off center.
and we place an electromagnet ring outside the tube
in the center so it will pull the piston towards it when
it is pulsed on and just before the piston reached the center
of the electromagnet it will turn off to allow 4 feet of motion
with only the friction slowing such down.
(we will call this one pulse)
The piston has a mass of 100 grams.
The tube, electromagnet, battery, and solar panels,
and container used to keep the battery charged
and all units contained will depend of course
upon thier components.
We will just say for this experiment that the rest of
the components will have a mass of 10,000 grams.
( yes this is an estimate since I don't have all these
choices picked out yet)

Now, if we pulse the magnet,
What speed would the larger mass reach after the pulse?


Given the Earth's magnetic field and proper orientation,
one can achieve any speed at all. One does not need the
piston, either; a magnetic coil interacting with the field
is sufficient.

Too weak for increasing the motion without waiting too long.

No time limit was stipulated in the above.

Yes, but we would want to move faster if possible right?

If possible, yes.






The main drawback is the amount of time necessary; as
the unit gains speed its orbit will increase in size.
Two acceleration pulses per orbit is all that's possible.
The best orbit is a polar one.

The drawback you create is caused by the removal of the
internal piston, there is no drawback of such in the device
I stated.
It simply needs to slowly move the piston back using
air pressure or another slower than the magnetic
pulse motion force.


Why air pressure? A solenoid moves the piston solely by magnetic
force.

I did not talk about it yet because I was waiting to see who would
actually notice the motion could occur in such.

The motion internally is easy enough; one can
contemplate half a dozen methods, from a solenoid to a
gunpowder-powered bullet.

All are doomed to failure absent ejection of part of
the mass.

Of course to get a second pulse, we would need to move the piston
back to the starting point, but we can not move it the same speed it moved
to begin with because that would stop the motion completely.


Move it slowly or quickly, smoothly or jerkily, all at
once or in millions of pieces; absent an external magnetic
field, or ejection of part of the mass, it won't work.

integral(t) sum(k) piece_k * vel_k(t) = 0.
Always.
