Magnets are used in everyday life, and heat is everywhere no matter where you go on Earth. Knowing the best temperature to use magnets is important for its efficiency. According to a HSI Sensing experiment, temperature rising seems to correlate with the decreasing of magnetism, and thus the magnetic pull, of the magnet. On the other hand, colder temperatures don’t do much, but can usually help magnets to focus on fixed points. Magnetism is the physical effect made by magnetic fields, which is formed by the electric currents and the magnetic moments of elementary particles. It comes in many types: ferromagnetism, ferrimagnetism, paramagnetism, and diamagnetism. Ferromagnetism is a certain type of magnetism that forms permanent magnets. Ferrimagnetism, though, is the opposite. It is defined as atoms with opposing magnetic moments. Paramagnetism is simply a slight magnetic pull and manipulation that is done thanks to the unpaired electrons attracting with other magnets. Differently, diamagnetism is the tendency for materials to oppose a magnetic field and is seen in all materials. With these in mind, there is one binding quality that encircles them all: their electron density and magnetic field. “Magnetism is a physical phenomena arising from the force caused by magnets, objects that produce fields that attract or repel other objects” (LiveScience). “Temperature is a measure of the average heat or thermal energy of the particles in a substance” (CalTech). In connection to magnetism, the Curie Temperature, or Curie Point, is the point of which the magnetism of a magnet changes drastically enough to permanently affect its magnetism, usually by stripping the property away immediately. Néel Temperature, on the other hand, is simply the temperature of which heat is taken by the magnet in the first place. Heat is the quality of being hot, or high temperature. The density functional theory involves electron density. It is defined as a computational quantum mechanical modelling method used in physics, chemistry and materials science to investigate the electronic structure of many-body systems. In relation with magnetism, they divide to the current density functional theory and magnetic field density functional theory. They both depend on the magnetic field and electron density. With this assortment of information, the relationship between magnets and temperature is the decreasing and increasing movement of magnets’ magnetic particles. Most magnets are dipoles, a pair of oppositely charged particles seperated by distance, in which results their magnetic molecules into facing a certain direction. When heating magnets, though, those polar molecules start moving around, spazzing out more and more as the temperature rises. The magnet’s whole polarity becomes messier without the proper focus. What a metaphor. On the other hand, in cold temperatures, nothing much will change. As it becomes more frigid, though, it may even support the magnet’s focus, improving its magnetic strength field towards a particular direction.
