Electromagnet technology

With electromagnets comes a very potent work system for any business. Electromagnets would be utilized for Braking systems, Heavy lift Jacks, propulsion systems, Rock crushing Limited distance propelled rods, rods projected for food crushing, and air compressors, pumps, gears, and any device that utilizes any type of movement. Electromagnets may range from 1 Psi to trillions of psi. They may range in sizes also. Electromagnetic devices are very well under normalized conditions; yet falter under special conditions experienced in space when energy may be depleted from the magnet.
