Researchers repurposed an experiment originally intended to detect gravity, which involved a floating magnet in a superconductive trap, predicting that gravity exerted by dark matter would interact with the magnet. The experiment is now being upgraded from a gravity detector to a dark matter detector, so expect version 2.0 soon. When gravitational forces exerted by bodies in space are beyond what is expected, dark matter is the explanation (but never the evidence).

This method uses a magnet floating in a chamber made of superconductive material.
