AbstractA electromagnetic machine is provided. The machine has a rigid elongated hollow shell, open at both ends, which is bigger at its midsection than at either end. The shell is wrapped with a wire which is connected to a power source so that the device can be energized. A pliable elongated pouch is at least partially within the shell and the two ends of the pouch protrude from the open ends of the shell. Magnetizable particles are contained within the pouch. When current is flowed through the wire, the particles are attracted radially outward at the biggest section of the shell. As the particles move they deform the pouch and the two ends of the pouch are brought closer together. Work can be performed by attaching objects to the two ends of the pouch.
