👉 In physics, a "remagnetized" object is one that has been magnetized by external fields. This can be thought of as a magnetic field being applied to an object and causing it to become more or less magnetic depending on the strength of the field. For example, if you place a magnet near a piece of iron, the iron will start to feel the magnetic force from the magnet, and this phenomenon is known as "remagnetization." If you then move away from the magnet,
