How, according to Ampere’s hypothesis, distinguish between magnetized and non-magnetized bodies?

| According to Ampere’s hypothesis, a lot of closed circular currents constantly flow in bodies of iron, steel, etc. Each such current creates a weak magnetic field, that is, there are always many extremely small elementary magnets in the body. In a non-magnetized body, elementary magnets are located chaotically, and their fields cancel each other out. Such a body has no magnetic field. When the body is magnetized, the elementary magnets are oriented in one direction, the body becomes a magnet.
