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 will flow forever in a closed loop of superconducting material, hence the high demand of such a product.
The development of superconductors has been a working progress for many years and some superconductors are already in use, but there is always room for improvement. In 1911, Dutch physicist Heike Kamerlingh Onnes first discovered superconductivity when he cooled mercury to 4 degrees K (-452.47º F / -269.15º C). At this temperature, mercury’s resistance to electricity seemed to disappear. Hence, it was necessary for Onnes to come within 4 degrees of the coldest temperature that is theoretically attainable to witness the phenomenon of superconductivity. Later, in 1933 Walter Meissner and Robert Ochsenfeld discovered that a superconducting material will repel a magnetic field. A magnet moving by a conductor induces currents in the conductor, which is the principle upon which the electric generator operates. However, in a superconductor the induced currents exactly mirror the field that would have otherwise penetrated the superconducting material - causing the magnet to be repulsed- known today as the “Meissner effect.” The Meissner effect is so strong that a magnet can actually be levitated over a superconductive material, which increases the use of superconductors. After many other superconducting elements, compounds, and theories related to superconductivity were developed or discovered a great breakthrough was made. In 1986, Alex Muller and Georg Bednorz invented a ceramic substance which superconducted at the highest temperature then known: 30 K (-243.15º C). This discovery was remarkable because ceramics are normally insulators – they do not conduct electricity well. Since their discovery the highest temperature for superconductivity to occur is 138 K (-130.15º C).
The uses of superconductors are innumerable. They are used in the medical field often, so their use if valuable to common citizens such as yourself and me. Their uses medically include MRI (Magnetic Resonance Imaging) so that doctors do not have to invade the human body for exams, as well as speeding the results of the exams to almost instant information.
Furthermore, AMR should be recognized as the combined solid -fluid system, whereby, in essence, a temperature gradient is established throughout the AMR and a fluid is used to transfer heat from the cold end to the hot. This subtle but important idea produced a new magnetic cycle distinct from Carnot, Ericsson, Brayton, or Stirling [6].
Nuclear energy is used today for energy supply and about 15% of the world’s energy comes from nuclear power plants some forms of medicine such as nuclear medicine rely solely on nuclear technology. This technology was developed through the process of creating the first atomic bomb and would not exist if not for the advancements made during the Manhattan project.
These lasers can be used for such things as to reduce abnormal eye pressure, to treat glaucoma (an eye disorder), and to repair failed glaucoma surgeries. Holmium is also used for its ability as a magnet. For example, holmium may be used in a high strength magnet such as in a magnetic-flux concentrator to create a strong artificially generated magnetic field. It may also be used in the future since scientists are still learning more about this elements distinct magnetic properties. But, for now all we know about holmium is that it has no role biologically and that it is also not toxic. Scientists however have suspicions that holmium may stimulate
Finally, gold parallels my goals for the future. It is one of the most conductive metals, extremely well suited for carrying an electric current. I, too, aim to conduct another kind of electricity-political organization, by pursuing a degree in Political Science at Harvard.
treatment of disease and for determining clinical pathways and other fields of science. Even though
During the late 1970's, the world of diagnostic imaging changed drastically due to the introduction of Magnetic Resonance Imaging, also known as MRI. For over 30 years, they have grown to become one of the most significant imaging modalities found in the hospitals and clinics ("EDUCATIONAL OBJECTIVES AND FACULTY INFORMATION"). During its ancient days, these machines were referred to as NMRI machines or, “Nuclear Magnetic Resonance Imaging.” The term “nuclear” comes from the fact that the machine has the capability of imaging an atom's nucleus. Eventually, the term was dropped and replaced with just MRI, because “nuclear” did not sit well with the public view ("EDUCATIONAL OBJECTIVES AND FACULTY INFORMATION"). Many people interpreted the machine to produce an excess amount of radiation in comparison to the traditional X-ray machine. What many of them were unaware of, MRI does not disperse a single ounce of ionizing radiation making it one of the safest diagnostic imaging machine available to this date. MRI machines actually use strong magnetic fields and radio waves to produce high quality images consisting of precise details that cannot be seen on CT (Computed Tomography) or X-ray. The MRI magnet is capable of fabricating large and stable magnetic fields making it the most important and biggest component of MRI. The magnet in an MRI machine is measured on a unit called Tesla. While regular magnets commonly use a unit called gauss (1 Tesla = 10,000 gauss). Compared to Earth's magnetic field (0.5 gauss), the magnet in MRI is about 0.5 to 3.0 tesla range meaning it is immensely strong. The powerful magnetic fields of the machine has the ability to pull on any iron-containing objects and may cause them to abruptly move with great for...
In the passage How a Melted Bar of Chocolate Changed Our Kitchens, it states that an engineer named Raytheon invented Magnetrons which was no mistake at all, but what came after was indeed a mistake. Percy Spencer was standing next to a Magnetron and felt the heat that it gave off. He found that it melted his chocolate bar he had. He put two and two together and asked for popcorn kernels. He put the kernels next to the Magnetron and minutes later there was popcorn.
Superconductivity, a similar phenomenon, was discovered in 1911 by Dutch physicist Heike Kamerlingh Onnes. When he cooled some mercury down 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 reach even higher superconducting temperatures. Currently, the highest temperature at wich a material can be superconductive is 138K, and is held by the compound Hg0.8Tl0.2Ba2Ca2Cu3O8.33.
The largest and most powerful particle collider in the world, based in CERN on the border of France and Switzerland, it is a huge undertaking. It is built to assists the scientists in discovering what the Earth is made of; it also plays a crucial part in resolving many theories by scientists. It is a 27 kilometer ring with super magnets that help the particles speed along the way. Some people also argue that it’s a machine that could possibly be dangerous, because it has the capability of creating small BLACK HOLES! “One way or another, it's the world's largest machine and it will examine the universe's tiniest particles. It's the Large Hadron Collider (LHC).”
All atoms have a nucleus, which orbited by spinning electrons and as the magnet increases in temperature the distance between the nucleus and the electrons increase therefore decreasing the strength of the magnet.(1) Equipment: Magnet Hot Plate Tongs
Some materials have a feature known as ferromagnetism. The prefix "ferro" refers to Iron, which is one such material. Ferromagnetic materials have the ability to "remember" the magnetic fields they have been subjected to.
Electricity and electrical components are a major part of our lives today. Our lives pretty much come to a halt if there is a power outage or if our electrical devices stop working, sometimes we even start panicking because we are so dependent on these components that we cannot afford to lose them and their importance and use only increases as time passes. We all use these electrical devices and also electricity itself but most of us do not think about the math and physics that works behind all of these things.
The Tesla coil was made by Nikola Tesla in 1891. Tesla was a scientist that believed the ground and Earth were better conductors than metals. Therefore, he created the Tesla Coil which was a device that could send electricity to appliances without cords or wires. This device was able to power lights or other things that required electricity from several feet away. The Tesla coil looks like a mushroom with a metal top and copper wire coiled around the center of it. A Tesla Coil if tweaked can make electrical currents go through your body, make electron winds, or shoot lightning bolts. Altogether the Coil was made so the world wouldn't have wires everywhere. Imagine a world with no wires, there wouldn’t be things you could trip over and no telephone
