For example - if one were to generate an electromagnetic field using super-cooled magnets, and the magnets were shut off, is it possible for another field to interact with the collapsing one and essentially fire the remains out of a theoretical barrel like a shotgun? This would require each field to be opposite in polarity. And if so, would this generate any kind of measurable force and if so, would ramping up the power of the magnets produce more?
Edit: A better way of asking this would be this: Can a magnetic field hold a positive or negative charge strong enough to affect a magnet (as in pushing it away or attracting it) due to the polarization of the field? And if so, will two fields of similar charge repel each other?
After further thinking: Looking to the planet, we know that the north pole and south pole are strong magnetic fields and compasses work because magnetic metals are attracted or repelled by these fields. In theory wouldn't it be possible to generate a strong magnetic field that behaves in the same manner?
UPDATE: After doing some further research the reason behind this question has actually been answered and in fact tested and proven to work, though scientists only have theories as to why since it doesn't follow conventional thinking. Nasa has developed an EM drive which uses electromagnetic fields to generate thrust. Though my thought was that something similar could be done by using multiple fields, I'm not entirely sure how this particular system works. But it's a good read for anyone interested and this does open the doors for long term space flight without the need of fuels.
