Synthetic Magnetosphere Generators

Ok this is just magic I can't really justify ships having gravity but what can I say I think captains standing on bridges looks cool sue me. However despite that I've tried to make the gravity on ships at least a bit more interesting, always originating from a single line down the centre of ships and flowing out in a wave whose peak is at the crew areas of the ships and troughs are closer and further on from that line. That way ships have to be designed around the gravity generator and have the gravity sensitive equipment and weapons in the centre or at the bottom of the ship (CAMs or sensors etc) which makes ships take on some fairly interesting designs hopefully. If you want to not use an
