Abstract
A device for removing a material stuck to the wall of a receptacle comprises an electromagnetic coil (1) connected to a pulsed current source (2) and provided with two short-circuited loops (5, 6) made of a non-ferromagnetic material. One loop (5) embraces the external loop of the spiral (3) of the coil (1) and the other loop (6) is located inside its central loop. The body (7) of the coil (1) is connected to a plate (8) made of a paramagnetic material of high electroconductivity and mounted movably between the coil (1) and the wall surface (9) of the receptacle treated.
