Magnetic FieldsDefined 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 TrainsMaglev = Magnetic LevitationThree primary functions
Levitation or suspensionPropulsionGuidance

Maglev TrainsFirst 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 TrainsRelieve traffic congestion
Travel at speeds of 300 mph non-stop until destination
Very safeMany redundancies are integrated into the system
ensuring that the magnets continue to workThe 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
![Page 7: By Chris Pewick. Nathan Martens, and Cassie Ulfe](https://reader036.vdocuments.net/reader036/viewer/2022081514/56649cc25503460f94989f0e/html5/thumbnails/7.jpg)
Maglev Heart TransplantThe 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

Maglev Heart TransplantHas been used in over 70 patients in Europe
The first American to receive the transplant was Anthony Shannon on July 30th, 2008Connected 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

The Large Hadron Collider
![Page 11: By Chris Pewick. Nathan Martens, and Cassie Ulfe](https://reader036.vdocuments.net/reader036/viewer/2022081514/56649cc25503460f94989f0e/html5/thumbnails/11.jpg)
Particle AcceleratorsThe 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
![Page 13: By Chris Pewick. Nathan Martens, and Cassie Ulfe](https://reader036.vdocuments.net/reader036/viewer/2022081514/56649cc25503460f94989f0e/html5/thumbnails/13.jpg)
Particle AcceleratorsTwo 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, additional dimensions and the string theory.
They are guided around the accelerator ring by a strong magnetic field, achieved using superconducting electromagnets

Rocket Launch railsUsing tracks similar to those used in maglev
transportation rockets, shuttles and satellites could be launched into orbit
![Page 15: By Chris Pewick. Nathan Martens, and Cassie Ulfe](https://reader036.vdocuments.net/reader036/viewer/2022081514/56649cc25503460f94989f0e/html5/thumbnails/15.jpg)
Rocket Launch RailsA 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

ConclusionMaglev 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
