Sadly it's not enough to have a force; it needs to produce a motion (to perform work). Think of the analogy with a ball feeling gravity at the top of a hill: it has the potential to release energy but it remains unrealised until it starts rolling downhill. Once in motion energy can generated, say by coupling it to a dynamo, but once the ball is at rest at the bottom then even though it still feels gravitational attraction there is no power output.
