  Yes there are force fields. The most basic example is if you put a magnetic next to something magnetic it moves towards the magnetic. This is the magnetic force field in action. There are also electric force fields and some more exotic ones such as symmetry fields.
  I don’t watch much scifi so I hope that answers your question.
