High temperatures tend to destroy the magnetic fields. Tere are lots of similarities between magnetic polarization effects and polarization effects. Te electric dipole moments of electric dipole usually start the behavior of dielectric materials. Te domain moments in the dipole are aligned causing a form of polarization. Terefore I can say that polarization is the process where the dipoles align themselves in the magnetic domain. Tis polarization produces a resultant field that appends the applied field. Wile dielectric materials reduce an applied electric field, tpical magnetic materials will tend promote an applied magnetic field.
Tese materials may be termed as paramagnetic. Uder the normal room temperatures, auminum and sodium are seen to be paramagnetic. Ion oxide will also behave in the same manner. Wth such an insight, Ion oxide will be my representative paramagnet. Ishould expect the polarization to remain in materials like nickel and iron even after the magnetic field has been removed. Tese materials are therefore termed as ferromagnetic. Frromagnetic materials generally promote an applied magnetic field, bt their capacity to hold a permanent polarization cannot fully explained.
Ican then conclude that ferromagnetism acts as a limiting factor to paramagnetic materials. Te guiding rule is that, al paramagnets must become ferromagnetic at defined lower temperatures. Fr such a situation in which the genesis of a magnetic dipole moment is clearly put into consideration, te moment is said to be caused by a direct circulating current. Te most crucial similarity between dielectric and paramagnetic objects is the association between the consequent polarization and the applied field. Uing the example of Maglev, i is seen that a can be dragged a little bit from the path using a magnetic field, trough the creation of thrust and lift.
Mglev trains movements are smooth and at times more quieter than the normal wheeled systems. Teir non-dependency on friction means that deceleration and acceleration can go far much beyond that of wheeled transports. Tey are also unaffected by weather. Although typical wheeled transportation can travel very quickly, amaglev system promises even greater speeds than the traditional rail. Te result is what I may term as the record for rail Tains with vacuum tubes systems will most definitely give necessary time...
