destroyed if a sufficiently strong magnetic field is applied. A metal in this state has very unique magnetic properties that are unlike those at normal temperatures. A superconductor is often referred to as the perfect diamagnetic. Diamagnetic, ideally, are a class of materials that do not conserve magnetic flux, but expel it. A superconductor is classified as a perfect diamagnetic because by all measurable standards the magnetic flux within the material is zero. Electrons have a wave-like nature
I am writing to inform you of a recent economic opportunity that could leave you rich if you choose to invest. The prospect of wealth relies on superconductors- the system of the future and present. You could earn millions by contributing to the research of superconductors. Superconductors consist of an element, inter-metallic alloy, or compound that will conduct electricity without resistance (loss of energy flowing through the material) below a certain temperature. Once in motion, electrical current
Super conductivity is a natural phenomenon in which certain materials such as metals, alloys, and ceramics, can conduct electricity without resistance. These materials are what we call superconductors. In a superconductor, once the flow of electrons begins, it essentially goes on forever, making it an important material to humans. Superconductivity was discovered by a Dutch scientist by the name of Heike Kamerlingh Onnes in 1911. While researching properties of materials at absolute zero, this man
New Superconductors: Advances, Issues, Limitations Report by Amber Taylor CHME 5699 Dr. Laura Lewis Final Report 23 April 2014 Executive Summary One of the most exciting and magical phenomena observed today in science is the levitation of superconductors in the presence of a magnetic field. While entertaining, this effect is also extremely useful and could combat one of the largest issues facing the world today: how can we continue to transport goods and people without burning fossil fuels
to liquid helium temperatures, it began to conduct electricity with no resistance at all. People began experimenting with other metals, and found that many tranisition metals exhibit this characteristic of 0 resistance if cooled sufficiently. Superconductors are analagous to superfluids in that the charges within them move somewhat like a superfluid - with no resistance through sections of extremely small cross-sectional area. Physicists soon discovered that oxides of copper and other compounds could
mathematical framework or set of rules for the construction of physical theories and is the foundation of the quantum computer. It is an indispensable part of science and has been applied to the structure of the atom, nuclear fusion in stars, superconductors, the structure of DNA, and the elementary particles of nature (Nielsen 2). Since the 1970’s developments in techniques for controlling single quantum systems have occurred. For example there have been methods developed for trapping a single
physicist Heike Kamerlingh Onnes discovered that the resistance of mercury absolutely disappears at temperatures below about 4K. This phenomenon is called superconductivity; correspondingly, materials which have this property would be called superconductors. Because of this great discovery, in 1913, he won a Nobel Prize in physics for his research in this area. [2] The technological development of superconductivity was hampered by the cost of producing the extremely low temperatures required to achieve
matter: solid, liquid, gas, and plasma. Fortunately this is not true as that would be boring. There are also at least 4 other-less common states and Icontest a fifth. These are Bose-Einstein condensate, photonic molecules, quark-gluon plasma, superconductors, and superfluids. They all have unique properties that clearly distinguish differences between them and the traditional four states. These breakthroughs could help us in the future and have some practical uses right now. My personal favorite
Essentially every single device that humans use to make their life easier can be greatly attributed to the field of physics for its inception. The laws of physics govern everything that we use, see, and observe life as we know it would not be possible without it. Multiple branches of physics exist, but one stands out as the branch that has the most promise to deliver devices well beyond even our wildest imagination, electricity and magnetism. Someone who has not been educated a great deal on the

Metal Ore An ore is any kind of rock or mineral from which a metal can be profitably extracted. Metals are rarely found uncombined (as elements) in nature. They are nearly always present in the forms of compounds, often where the metal is chemically joined with oxygen. Only the most unreactive metals, like silver and gold will be found pure. The most common metals are oxides and sulphides. Ores are rocks from which we extract metals. Metals are found naturally in rocks called ores. They
attempt to assimilate native people. Avatar was directed by James Cameron, and was released on December 18th, 2009. In short, humans from Earth travel to a far-off planet, Pandora, specifically to mine a mineral called unobtainium, which is a superconductor. Given how humanity treat the Na’vi as a lesser
known as the guide way, is fitted with wire coils that are in the shape of an 8 and run parallel to a superconducting magnet that is fitted to the underside of the train with. The current induced in the wire coils by the magnetic flux from the superconductor creates a magnetic field, but because the wire is in a figure 8 shape, the top and bottom of the 8 have magnetic fields in opposite directions. The superconducting magnet is given the same magnetic field as the bottom loop of the 8. A diagram
Cryogenics comes from the combination of two different Greek words, namely “kryos”, which means very cold or freezing and “genes” means to produce. Cryogenics is thus defined as the branch of physics and engineering which deals with the study of very low temperature (below 123K), their production and the materials behavior at such low temperature. 1.1. Cryocooler Cryocoolers are refrigeration machines/equipment having very low achievable refrigeration temperature (below 123K) and low refrigeration

Niobium, an element a confused early past. It was named after the Greek mythological figure of Niobe, Niobe was the daughter of Tantalus. The reason Niobium was given this name was because the element itself had remarkably alike chemical properties to the element Tantalum. However it was formerly named Columbium, this was the element’s common name in America. In comparison, the name of Niobium was more frequency in use in Europe. However, such debate over the name of the element came to an end in
Electrical Resistance Electrical resistance is a property of an electrical circuit that opposes the flow of current. Resistance involves collisions of the current-carrying charged particles with fixed particles that make up the structure of the conductor. Resistance is often considered as localized in such devices as lamps, heaters and resistors in which it predominates, although it is a characteristic of every part of a circuit, including connecting wires and electric transmission lines
Henry Taube was born on November 30, 1915 in Neudorf, Saskatchewan, Canada. He was born into a family a four boys and was the youngest. His parents were Samuel Taube and Albertina Tiledetzski. Taube left Neudorf at a young age of twelve years old and moved to Regina. There, he went to Luther College and finished high school. He took first year university classes at Luther College since he had a position as a laboratory assistant for a man named Paul Liefeld. While he lived in Canada, he studied at
Numerous factors influence electrical conductivity and resistance, two of them are temperature and length of the wire (these are external factors). Electrical conductivity is defined as the property used to describe how well materials allow electrons to flow, and the degree to which a specific material conducts electricity., Electrical conductivity is calculated as the ratio of the current density in the material to the electric field that causes the flow of current. The SI unit of electrical conductivity
