MAGNETIC LEVITATION AND TRAINS BY: MANISH KUMAR 2K12/EE/075 Delhi Technological University INTRODUCTION MAGLEV = MAGNETIC + LEVITATION Magnetic means “based on magnets” Levitation means “to rise and float in air” Maglev is a method of propulsion that uses magnetic levitation to propel vehicles with magnets rather than with wheels that the conventional trains use. Magnetic levitation is the use of magnetic fields to levitate a (usually) metallic object. Manipulating magnetic fields and

containing one of those materials so it an come together. If two magnets align it it is considered to be called a magnetic field. Compasses are used by magnetic fields coming from the North and South Poles. The way magnets come together is magnetic pulls. Examples have you ever tried to push two magnets together? Usually they go to the right or left. That is because there are magnetic fields pushing off of each other. If you just lay them down next to each other they will connect because you are not

Hendershot Fuel Less Generator 2 Hendershot Fuel Less Generator What is a fuel less generator? All over the world‚ people live with the idea that it’s necessary to burn fuel in order to produce power that we can use. We have been persuaded that we have to buy coal‚ coke‚ timber‚ kerosene‚ gasoline‚ diesel‚ propane etc to burn‚ so that we can obtain our precious energy. And yes‚ it is perfectly true that burning these materials will indeed result in energy. And yes‚ we need it

Magnetic bearings: The lubricated bearings in ordinary systems is replaced by a digitally controlled magnetic bearing system‚ consisting of both permanent magnets and electromagnets. the compressor shaft” being the only rotating part is is levitated and held in place by magnetic bearings.

(1) an electric current or a charging electric field produces a magnetic field or (2) a charging magnetic field produces an electric field. In 1820‚ the Danish scientist Hans Oersted discovered that a conductor carrying an electric current is surrounded by a magnetic field. When he brought a magnetized needle near a wire in which an electric current was flowing‚ the needle moved. Because a magnetized needle is moved by magnetic forces‚ the experiment proved that an electric current produces magnetism

the outer core fluid is not fully understood. Some researchers have linked rotation of Earth‚ due to "original spin" at the time our solar system formed‚ to the rotation of the outer core. Circulating magma in the molten outer core generates a weak magnetic field‚ which the researchers suspect may be leaking into the inner core and generating an electric current. The twisting force generated by this electromagnetic interaction may be what drives the inner core’s rotation.” Third‚ the Marianas Trench

Some materials have a feature known as ferromagnetism. The prefix "ferro" refers to Iron‚ which is one such material. Ferromagnetic materials have the ability to "remember" the magnetic fields they have been subjected to. An atom consists of a number of negatively charged electrons‚ orbiting around a positively charged nucleus. These electrons also possess a quantity known as spin‚ which is roughly analogous to a spinning top. The combination of orbital and spin motions is called the angular momentum
