Is it possible to use earth's magnetic field to overcome gravitational field of earth and go into outer space? And since whole universe is filled with magnetic fields from galaxies, clusters and super-clusters, can we use that to navigate our spacecraft in the outer space? We can create a powerful magnetic field around the spacecraft and control the shape of the field so as to repel from the earth's magnetic field in required direction. Once we reach outer space (away from earth's magnetic influence), we can change the craft's magnetic field so as to utilize sun's magnetic field for propulsion.
