Is it possible to use magnates as part if a docking port on a space station????

yes you could use them as PART of the docking system.

computers or people would have to control the propulsion system to navigate the ships together, and from that point, the magnets could be used to align the last few millimeters and "snap" everything into place

magnets could NOT be used to "guide" the whole process.

distances would be too far.

more distance = more possibilities of mistakes

more distance = larger magentic field = more possibilities of mistakes

larger fields requires more energy and can damage other computer systems on both of the ships.

also --------- if you activated a magnet to pull a ship in, the second you turned it on, the other ship would advance at a VERY high velocity VERY quickly. You could not apply enough energy to reverse the ship quick enough to stop the ship if something went wrong.

It could and probably WOULD crash into the dock, damaging multiple systems on both ships.

You probably could not use permanent magnets as part of a docking port on a space station. However, with proper design considerations you could feasibly use an electro-magnetic docking system.

Theoretically yes but it would have to be a very big magnet. And there is a chance that magnets might mess up the computers in the ship.

Electro- magnets would be feasible but there would be too much weight involved to make them practical.

no .. because it will close all the things around not only a specific one ...
