Maglev trains are extremely environmentally friendly as they have zero carbon emissions, since they run on electricity. Maglev trains also reduce noise pollution compared to regular trains. What…
Despite over a century of research and development, currently high-speed maglev is only available in China and maglev transport systems are now operational in just three countries (Japan,…
In Maglev, superconducting magnets suspend a train car above a U-shaped concrete guideway. Like ordinary magnets, these magnets repel one another when matching poles face each other. What…
Answer: Electricity is used to create electromagnets. The electromagnets are used on the track for a maglev train. Some maglev trains are levitated by magnetic repulsion. Other maglev…
Gradient coils are used to spatially encode the positions of protons by varying the magnetic field linearly across the imaging volume. The Larmor frequency will then vary as…
Gradients are simply loops of wire or thin conductive sheets on a cylindrical shell that lies just inside the bore of an MRI Scanner. When an electrical current…
Although MRI does not emit the ionizing radiation that is found in x-ray and CT imaging, it does employ a strong magnetic field. … Patients should notify their…
The magnetic fields that change with time create loud knocking noises which may harm hearing if adequate ear protection is not used. They may also cause peripheral muscle…
A magnetic resonance imaging (MRI) scan uses a combination of radio waves and strong magnetic fields to create an image of inside the body. … Short bursts of…
NMR spectroscopy was originally developed to help chemists who had created strange compounds that they couldn’t identify. In the technique (and just as in MRI), an unknown sample…
