👉 The term "ephase" is used in physics to denote a phase change between two states. It refers to the transition from one state of motion or configuration to another, often due to an external force acting on an object. In the context of electromagnetism, an "ephase" can be defined as the transition from electrically charged particles (like electrons) in one region of space to neutral particles in a different region of space, typically due to the presence of a magnetic field that opposes
