Paramagnetism Research Paper

Diamagnetism can make levitation possible. How? Diamagnetic materials are repelled by magnetic fields. The most diamagnetic materials are graphite and bismuth. Technically, everything is diamagnetic but the force of it is very weak. Diamagnetism is present in everything, but is only observable if other types of magnetism, such as paramagnetism, ferromagnetism, ferrimagnetism, antiferromagnetism, etc. do not overwhelm it. Most of the time, diamagnetic materials’ effect is very weak. Levitating humans are possible with this, since we are mostly water and water is diamagnetic, but the magnetic forces required would be enormous due to the relatively weak force of repulsion. Overall, diamagnetism sounds pretty awesome, right? Well, it’s a lot …show more content…
In ferromagnetism, ferromagnetic materials strongly attract each other in an external magnetic field. The reason why the strongly attract each other is because of the presence of magnetic domains. In these magnetic domains, the atoms are aligned so that the magnetic force is strong, however when unmagnetized, the atoms are positioned randomly and the net magnetic field is zero. Ferromagnetic materials are fairly common and the most well-known ones are iron, nickel, and cobalt. Paramagnetic materials slightly attract each other in an external magnetic force. The characteristics of paramagnetic materials are caused by unpaired electron pairs. Electrons are found in pairs most of the time, when they are paired and the electrons are circling the nucleus in opposing directions, they cancel each other out and therefore no magnetic reaction happens. When there are unpaired electrons, they may have a reaction to external magnetic fields, the reaction can be categorized as diamagnetic, ferromagnetic, or paramagnetic. In diamagnetism, all the electrons are paired, but they do have a reaction since they change direction when the external magnetic field is added so the “like” poles match and repel. This is similar to magnetic domains in ferromagnetic materials. In ferromagnetic materials, their magnetic domains align in a certain way when they are …show more content…
For example, in 2002, in Shanghai, the world’s first MagLev, short for Magnetic Levitation, train opened. These trains have many more advantages and benefits compared to standard rail trains. Since the MagLev trains do not actually make contact with the surface, much less maintenance is needed to operate them. They also are better for the environment since the emit no pollution. This is an example of an actual and practical use for Magnetic Levitation, as a form of transport. Hovercars are actually possible with this, making it a much more environmentally friendly and safer form of
