Abstract
Tato bakalářská práce se zabývá vlastnostmi permanentních magnetů, materiály, ze kterých jsou vyrobeny, jejich využitím v praxi a vzájemnou interakcí mezi magnety a jejich okolím. Teoreticky zpracovává jev vzniku magnetického pole a jeho chování v látkovém prostředí, zejména se pak věnuje feromagnetickým látkám a permanentním magnetům z nich vyrobených. Z praktického hlediska se zabývá ověřením vlastností permanentních magnetů, zejména remanentní magnetické indukce a porovnáním neodymových, samarium-kobaltových a feritových magnetů. Demonstrace magnetických polí pomocí zobrazování flux detektorovou fólií, železnými pilinami a kapalinou ferrofluid je názornou ukázkou rozmanitosti výroby permanentních magnetů a jejich možností využití. V neposlední řadě se zmiňuje o některých moderních hračkách jako je Levitron a NeoCube.
This bachelor thesis deals with characteristics of permanent magnets, the materials they are made of, their application and mutual interaction between magnets and surrounding area. Theoretically, it describes phenomenon of magnetic field formation and its behaviour inside the material environment, particularly ferromagnetic substances and the permanent magnets made of them. From a practical point of view, it deals with the characterization of permanent magnet properties, in particular, magnetic remanence and comparison of samarium - cobalt, ferrite and neodymium magnets. The demonstration of magnetic fields using flux detector foil, iron sawdust and ferrofluid liquid is an example of production diversity of permanent magnets and their use. Finally, it describes some interesting modern toys such as Levitron and NeoCube.
