Magnets made from soft materials such as soft iron or certain alloys are easy to magnetize but tend to lose their magnetism quickly. These types of magnets are called temporary magnets. They are easily magnetized in the presence of a magnetic field, but they lose their magnetism when the external magnetic field is removed. This is due to the ease with which the magnetic domains in these materials can align and then realign when the external field is removed, causing the magnetic properties to diminish rapidly.
