All of the known rules of physics say that this is impossible but
all of the "known" rules of physics have been wrong before so who
is to say. In theory if you could find a material that would
block magnetic forces, you could in fact create a machine that
power itself without any outside source of power. The problem is
in finding a material that can block magnetic fields and to my
knowledge no such material exists.

It was invented in the 50's. It's called Flubber. But nobody took it
seriously.

I thought that blocked gravity.

You're thinking of upsidasium.
