Magnetic Fields and their Applications By Chris Pewick. Nathan Martens, and Cassie Ulfe
Magnetic Fields • Defined by Our text, Conceptual Physics, as “The region of magnetic influence around a magnetic pole or a moving charged particle” • This region can be manipulated and utilized to improve many different aspects of our lives. Such as, transportation, medical procedures, and even space travel.
Maglev Trains • Maglev = Magnetic Levitation • Three primary functions • Levitation or suspension • Propulsion • Guidance
Maglev Trains • First proposed by Bachelet in France and Goddard in the United States in the early 1900’s • 1934 Hermann Kemper of Germany receives a patent for the magnetic levitation of trains • 1970 Test runs are conducted • 2004 Shanghai Maglev Transportation Development Co., Ltd. opens their maglev for public use
Maglev Trains • Relieve traffic congestion • Travel at speeds of 300 mphnon-stop until destination • Very safe • Many redundancies are integrated into the system ensuring that the magnets continue to work • The train has auxiliary wheel to start up that could provide a safe landing should the magnets fail • How it works
Maglev Heart Transplant • Terumo Heart, Inc. makes a transplant called a DuraHeart • A heart transplant that uses similar technology as the maglev train
Maglev Heart Transplant • The transplant uses a small paddlewheel-like component, called an impeller to propel the blood, this system runs more smoothly and gently than other heart transplants. • The paddle is suspended inside the device by magnets • Better prevents clots and blood cell damage which could cause internal bleeding • DuraHeart
Maglev Heart Transplant • Has been used in over 70 patients in Europe • The first American to receive the transplant was Anthony Shannon on July 30th, 2008 • Connected to his failing heart to help pump blood
Particle Accelerators • A particle accelerator (or atom smasher, in the early 20th century) is a device that uses electric and magnetic fields to propel ions or charged subatomic particles to high speeds and to contain them in well-defined beams • The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. It is expected to address some of the most fundamental questions of physics, advancing the understanding of the deepest laws of nature. • Consists of multiple circles the largest of which is approximately 17 miles in circumference • It is located along the border of Switzerland and France
Particle Accelerators • The Large Hadron Collider was built by the European Organization for Nuclear Research (CERN) with the intention of testing various predictions of high-energy physics. It was built in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories. • The LHC accelerator was proposed in the 1980s and approved for construction by the CERN Council in late 1994 • Digging began in 1998 and finished in 2003 • Construction of the collider finished in 2008
Detectors like this one are placed on various points of the collider and measure and record data from the runs
Particle Accelerators • Two beams of particles, propelled by magnets, travel at close to the speed of light with very high energies before colliding with one another • They can attain speeds of just 3m/s short of the speed of light • Studies and observations from the LHC could provide answers to questions regarding anti-matter, the big bang, mass of particles, additionaldimensions and the string theory. • They are guided around the accelerator ring by a strong magnetic field, achieved using superconducting electromagnets
Rocket Launch rails • Using tracks similar to those used in maglev transportation rockets, shuttles and satellites could be launched into orbit
Rocket Launch Rails • A full-scale, operational track would be about 1.5 miles long and capable of accelerating a vehicle to 600 mph in 9.5 seconds. • Drastically reduce costs of launching into space • Currently costs approximately $10,000 per pound to orbit payloads using rockets, with use of maglev technology this would go down to approximately $0.50 per pound
Conclusion • Maglev technology is used in a variety of different ways • Because of the high costs, it is very difficult to produce technology at such a sophisticated level. However, when this technology becomes commercialized, the prices could drop low enough for maglev technology to be used worldwide • We believe that this technology will eventually produce a positive out-come for our global society
