At the micro-level, what is the difference between an unmagnetized iron nail and a magnetized iron nail? In an unmagnetized nail, the magnetic domains have a random orientation so that the net magnetism adds to zero. In a magnetized nail, many of the magnetic domains are aligned. An unmagnetized nail is made of an isotope of iron that is not magnetic. A magnetized nail is made from a magnetic isotope. An unmagnetized nail is made of hard iron. A magnetized nail is made from soft iron. An unmagnetized nail is made of iron at low temperatures. A magnetized nail is made from iron that is hot
