# Hollywood physics

The Mission Impossible movies are typically filled with stunts that live on the edge of what seems possible. In the recent movie Ghost Protocol, one stunt involves an agent wearing a funky high-tech metal suit (it looks like some sort of chainmail). The agent is levitated off the floor using magnetic forces between the agent and a small robot sitting on the ground.

If I wanted to suspend a $$90~\mbox{kg}$$ secret agent in midair, what vertical force in Newtons must I exert on the agent, electromagnetic or otherwise?

Details and assumptions

• The acceleration due to gravity is $$-9.8~\mbox{m/s}^2$$.
