Tractor beam
A tractor beam is a device with the ability to attract one object to another from a distance. The concept originates in fiction: The term was coined by E. E. Smith (an update of his earlier "attractor beam") in his novel Spacehounds of IPC (1931). Since the 1990s, technology and research has labored to make it a reality, and have had some success on a microscopic level. Less commonly, a similar beam that repels is called a pressor beam or repulsor beam.
