👉 An argumentator is a type of device used in physics and engineering to measure the strength of an electromagnetic field. It consists of two parallel conductive plates, one with a conducting material and the other with a non-conducting material. The plates are separated by a gap between them. When a charged particle enters the gap between the plates, it is repelled by the electric field created by the second plate, causing the particle to move towards the first plate. This process is known as an electric
