Inventarea busola, cum funcţionează busola?

Ori de câte ori suntem în lume, ne puteţi găsi întotdeauna modul nostru prin intermediul busola într-un mod foarte usor. Chiar dacă am fost în mijlocul oceanului, ne ardura câteva secunde pentru a găsi drumul prin acest dispozitiv simplu. În zilele noastre busola a fost întotdeauna cea mai uşoară cale chiar dacă sunt dispozitive foartesofisticate, cum ar fi sateliţi GPS. Busola are o săgeată magnetice, care este echilibrat şi plasat deasupra acului, astfel încât se poate deplasa aproape fara frecare. Aceasta sageata, datorita magnetismului pe câmpul magnetic al pământului Nord (nord magnetismului), arată întotdeauna Nord.

 

Ne putem gândi lumea ca un magnet mare. Câmpul magnetic al lumii este direcţionat către un anumit ordin în procesul de formare şi arată o caracteristică de magnet. În consecinţă, Polul Nord este regizat ca S. Polul Sud este regizat, de asemenea, la N.Literele N si S utilizate în magneţii sunt, de asemenea, inspirat de Nord şi de Sud poli.

 

Busola este marcat ca N, la nord de săgeată, şi partea de nord a busolei atrage lumea Nord la principiul diferite poli trage reciproc. În scopul de a simţi acest împuşcat pe suprafața lumii, cu un diametru de 8000 de mile, săgeata busolei este extrem de usor si nu este fără frecare. Altfel, nu ar fi posibil pentru a naviga de câmp magnetic.

 

Întreaga axa a lumii, busola nu funcţionează cu precizie de 100 %, unele zone sunt abateri. Aceste regiuni şi cât de mult abaterea sunt afişate pe hărţi detaliate.

 

O considerare atunci când se utilizează compasul este lipsa unor obiecte de metal, care poate fi folosit pentru a crea câmpuri magnetice în jurul acestuia. În cazul în care câmpul magnetic în jurul busolei are un obiect care este mai mult decât suprafața Pământului, săgeata busolei este îndreptată spre acel obiect. Acest lucru înseamnă, de asemenea, defecte de măsurare.

 

Istorie

Chinezii inventat busola în 100 d.Hr. Descoperirea de busola s-a desfăşurat la principiul că un obiect eliberat ar fi indreptat spre nord într-un mediu magnetic.

 

În Franţa, prima busola a fost menţionat în 1200. Acesta a fost urmat de Islanda în 1207, Anglia şi 1213. Busola au o structură primitivă. Prima semnificativ de dezvoltarea fost Pierre de Maricourt (1269). După ce a pus acul într-un băţ de metal, a plantatîntr-o cutie transparentă şi clasificate.
