Well, technically the earths magnetic field is a force field deflecting solar wind…otherwise we would be toast.
I watched a youtube video on that very question a couple of months back. The gist of it was that it’s possible to replicate several aspects of the forcefield concept, at great expense and limited utility, but the full package is impractical and will be for the foreseeable future.
There’s a story floating around the internet, I can’t comment on its truthfulness, that 3M accidentally created one in one of their factories back in the 80s.
Allegedly the plant made adhesive tape, and as such had enormous rolls of plastic that were being spooled or unspooled by machines at very high speed, and at one point the right conditions existed for static electricity to build up in such a way that it created a sort of invisible wall that people were unable to pass through.
I wonder if this story, true or not, is related to the fact that peeling Scotch tape can produce x-rays.
Exactly where the notion came from.
This is interesting. Looks like its possible. Both dubious sources but it looks likely that other agencies are looking into it.

Electromagnetism is very flexible and theoretically you could put a lot of energy in a small place with it and there’s things like a strong enough magnetic field levitating a live frog.
That said it doesn’t seem very practical and it might not even be close to safe to walk around something with that much power like in the sci fi shows.
