Maglev cars depend on attraction and repulsion of magnets whose charge can be controlled. The power of electromagnets and certain/detrimental orientation can be manipulated by currents.

Overview
Maglev cars depend on attraction and repulsion of magnets whose charge can be controlled. The coercion of electromagnets and decided/colorless orientation can be manipulated by currents. Maglev technology requires an exotic type of an electromagnet that has nix resistance-a superconductor. These high-tech materials acquiesce for vehivle (or train) levitation and propulsion to speeds conventional transportation can't match. Nevertheless, there are one scientific and economic challenges that must be affected before maglev technology becomes extensive.
Electromagnets
Maglev cars (and trains) drudgery on a basic principle-substances shift Attractive when in fashion passes ended, and lose Attractive charge when now flow stops.At a low Sufficiently temperature, electromagnets lose all electrical resistence. Usually, much the top copper or gold wire has bitty resistence to current flow. This saps efficiency, and therefore magnet strength.
Electromagnets keep been used In good time maglev technology came along. A pleasant for instance of electromagnet employment is metal scrap yards using industrial-size magnets to pick up and Blop metallic misspend by simply flipping a switch that directs now to the Attractive pad.
Superconductive Materials
Superconducting magnets allow a perfectly smooth magnetic force correlating with perfectly uninterrupted current flow. Research is focused on designing electromagnets that are superconductive at higher-therefore cheaper to achieve-temperatures.Levitation
Technically, maglev cars fly. Mutually repulsive magnetic fields between the car and a pre-designed track-much like a rail track-force the car to float about an inch (depending on car weight and magnet strength) above the track. This design eliminates mechanical friction and allows speeds of several hundred miles an hour to be achieved.
Propulsion
Superconducting magnets alternate between opposite magnetic charge. Resulting magnetic attraction and repulsion serves to push-and-pull the magnetized car along the track. Accelerating, steering and braking is done by the same logic of magnets attracting/repelling the car to full speed and full stop. This process is synchronized by computers and sensors. Alongside propulsion materials, reliable computer programming and software/hardware interfacing is necessary for maglev cars (and maglev trains) to function properly.
Challenges
Problems with maglev cars are encountered among many new technologies. High costs and high possibility of financial failure are very prominent. In order to function on a wide scale, superconducting electromagnets will have to be cheap to manufacture and use. The whole maglev car ensemble would have to be profitable in a competitive environment. On top of that, there is a uniquely strong reliance on powerful magnetic fields. Health effects, as well as interference with nearby electronics, have to be addressed.
