I have been looking for info on whether or not magnets could be used to push objects (repel) and be made small enough yet powerful enough to say move furniture, or even a car. The idea would be to attach a small metal tab (removable) under said object and roll a small device to lift and move with magnetic power with ease. Could that be adapted into a pinpoint repel to push things at a distance. Could be used for space travel or even deflecting some asteroids (mostly metal) Any research would be greatly appreciated and if this has been done please forward any reference.. tyvm.
