Illustration of the right-hand rule for the Lorentz force, cross product of an electric current with a magnetic field. The working principle involves the acceleration of an electrically conductive fluid (which can be a liquid or an ionized gas called a plasma) by the Lorentz force, resulting from the cross product of an electric current (motion of charge carriers accelerated by an electric ...
Electromagnetic propulsion is utilized in transportation systems to minimize friction and maximize speed over long distances. This has mainly been implemented in high-speed rail systems that use a linear induction motor to power trains by magnetic currents. It has also been utilized in theme parks to create high-speed roller coasters and water ...
As magnets affect water to a small degree, and water containing ions is more conductive than purer water, magnetic water treatment is an example of a valid scientific hypothesis that failed experimental testing and is thus disproven. Any products claiming to utilize magnetic water treatment are absolutely fraudulent. [1]
Magnets attached to a vehicle's fuel line have been claimed to improve fuel economy by aligning fuel molecules, but because motor fuels are non-polar, no such alignment or other magnetic effect on the fuel is possible. When tested, typical magnet devices have shown no effect on vehicle performance or economy.
Induction motors do not use magnets, but permanent magnet motors do. The magnets found in permanent magnet motors used in electric vehicles contain rare-earth metals to increase the power output of these motors. [45] The mining and processing of metals such as lithium, copper, and nickel can release toxic compounds into the surrounding area ...
When the magnets are turned on, the iron particles in the fluid create a fibrous structure through the passages in the same direction as the magnetic field. The strength of the bonds between the magnetized iron particles causes the effective viscosity of the fluid to increase resulting in a stiffer suspension.

The Transrapid system uses servomechanisms to pull the train up from underneath the track and maintains a constant gap while traveling at high speed. Maglev (magnetic levitation) is a transportation system in which a vehicle is suspended on a guiding rail by the principle of electromagnetic suspension. Maglev has the advantages of being quieter ...
