👉 In physics, an ejector is a device that uses a magnetic field to displace charged particles from one point in space to another. These devices are often used in the context of particle accelerators and other experiments where high-energy particles need to be accelerated. The concept of an ejector was first introduced by physicist James Clerk Maxwell in his work on electromagnetism, where he proposed a method for accelerating electrically charged particles using a magnetic field. The idea was later refined and expanded upon by physicists
