As most people know (or don't know, whichever is the case) the component of an electrical circuit that causes energy loss is called "resistance," which can be defined as a materials opposition to current being passed through it. Usually, this resistance results in the production of heat, sound, or another form of energy. In many cases, this transformation of energy is useful in such applications as toasters, heaters, and light bulbs. Even though it is a useful property, resistance often gets in the way of performance in such cases as high voltage transmission wires, electric motor output, and other cases where internal system energy losses are unwanted. This is where the phenomenon of superconducting materials comes into play and may present the solution to this energy loss problem.

Superconductors are materials that display zero resistance under certain conditions. These conditions are called the "critical temperature" and "critical field," denoted Tc and Hc respectively. The Tc is the highest temperature state the material can attain and remain superconductive. The Hc is the highest magnetic field the material can be exposed to before reverting to its normal magnetic state. Within the substances currently known to superconduct, there is a divide between what has come to be called type I and type II superconductors. Type I are composed of pure substances, usually metals, and type II are composite compounds, usually some sort of ceramic.

Additional differences between type I and type II exist, mainly that type II display superconducting qualities at much higher temperatures and can remain superconductive in the presence of much higher magnetic fields. While type I have Tc's that hover just a few degrees from absolute zero, t...

...e the track and is propelled by the magnetic forces caused by the induced currents.

Another use of superconductors is in Magnetic Resonance Imaging, or MRI, in which the superconductor helps in creating a non-invasive method of looking at a persons brain activity.

Yet another area where superconductors would be especially helpful is in the power and electronics industry where power losses arise from a systems internal resistance. If a power generator was constructed with superconducting components the efficiency of the motor would be greatly increased. The electronics industry would benefit from faster switching times, smaller components, and greater circuit efficiency.

The world of superconductors is expanding at a tremendous rate. As the uses and possibilities for their use become more apparent, our society might see them more and more in everyday life.

Essay on Superconductors and Superconductivity - Before Kamerlign Onnes, in 1908, was able to liquefy helium and bring its temperature down to about 1K, it had been known that the resistance of a metal falls when cooled below room temperature. However, it was not known what value the resistance would approach if the temperature was reduced towards 0K until Onnes, while experimenting with platinum, discovered that, its resistance fell when cooled to a very low value that depended on the metal’s purity. As the temperature of mercury was reduced toward 0K, the value of the resistance would fall smoothly until the resistance fell extremely suddenly at about 4K....   [tags: physics science superconductor] 1569 words

Superfluids and Superconductors Essay - In 1924, the Indian physicist S. N. Bose developed an alternate law of radiation which modified Planck's laws to include a new variety of particles, namely, the boson. He sent off his theory to Einstein for revision and translation, and Einstein swiftly came up with some additions to the theory. He expanded the laws to incorporate the mass of the boson, and in doing so theorized a strange phenomenon. He predicted that when atoms of a gas came together under cold enough temperatures, and slowed down significantly, that they would all assume the exact same quantum state....   [tags: physics] 2386 words

Superconductivity and Superconductors Essay - Superconductivity and Superconductors ABSTRACT Superconductivity allows current to pass through a material with no resistive losses at near absolute zero temperatures. It also exhibits the Meissner effect which causes the superconducting material to repel magnetic fields. The application of this technology has been extremely limited due to the prohibitive costs of using Helium to cool the material to the critical temperatures....   [tags: Physics Physical Essays]

Essay about Advances in Superconductors and their Uses - Advances in Superconductors and their Uses A superconductor is an element or compound that will conduct electricity without resistance below a cretin temperature. The phenomenon was discovered in 1911 by Kamerlingh Onnes, who found that the resistance of mercury dropped suddenly to zero at a temperature of about 4.2°K. For the next 75 years there followed a rather steady string of announcements of new materials that become superconducting near absolute zero. A major breakthrough occurred in 1986 when Karl Alexander Müller and J....   [tags: Papers] 561 words

The Physics of the Arc Essay - ABSTRACT Several researchers have devoted efforts on studying physics of arc and descriptive models are used to explain many arc welding related phenomena. However, due to the subject complexity, doubts still emerge about the mechanisms of some phenomena related to the arc. For instance, the description about electromagnetic interactions with the arc, which governs the arc trajectory and lead to plasma jet and arc blow formation, seems to be yet controversial. Thus, the present study aimed a better understanding of these phenomena....   [tags: Physics ]

The Physics of Fishing Essay - The Physics of Fishing The use of a boat while fishing and some of the physics applicable to boating will be included in exploring the various ways physics applies to the sport of fishing. Other topics will include the fishing rod, fishing lure, casting, and the fish itself. The boat floats on the water according to Archimedes Principle which states an immersed object is buoyed up by a force equal to the weight of the fluid it displaces. The force applied downwards by earth’s gravity coupled with the upward force of buoyancy allows the boat to float....   [tags: Physics ]

Essay on The Physics of Roller Coaster - i: Introduction You apprehensively walk up the iron steps and onto the platform. You’re reluctant to go any further, but your friend eggs you on, saying, “It’s not that fast.” You step into the seat and pull the harness down over you. No, this isn’t the latest, greatest technological frontier. It’s a roller coaster. Since 1804 when the first wheeled roller coaster- called “Les Montagnes Russes”- was constructed in Paris, France, roller coasters have been a staple of adventure and fantasy among children and children-at-heart....   [tags: Physics] 1556 words

Superconductors Essay - Superconductivity is a property displayed by certain materials at very low temperatures. Metals and their alloys have been known to be superconductive (ex. Tin, aluminum) other materials that have also been found to be superconductive are ceramics which contain copper and oxygen atoms. Superconductors have a special property which is that they can conduct electricity without resistance which means that energy is not lost. Once in motion, energy can flow through a closed loop of superconductive material forever....   [tags: Technology ]

Applications of Physics For Different Industries Essay example - INTRODUCTION Physics attempts to describe the fundamental nature of the universe and how it works, always striving for the simplest explanations common to the most diverse behaviour. For example, physics explains why rainbows have colours, what keeps a satellite in orbit, and what atoms and nuclei are made of. The goal of physics is to explain as many things as possible using as few laws as possible, revealing nature's underlying simplicity and beauty. Physics has been applied in many industrial fields, which include the air industry, construction industry, automobile industry, manufacturing industry and many others....   [tags: Physics] 1954 words
