Tus magnetic compass yog hiob ntsuas rau navigation thiab lawm ib tug uas tseem ceeb heev rau cov navigators hauv hiav txwv rau centuries. Cov compass ships dejcawv daim npog sab xaiv kom tso cai rau. Los ntawm kev noj khoom pom bearings nrog ib compass, cov navigator no tau kho txoj hauj lwm los ntawm ib lub nkoj nyob rau ib daim ntawv.

Ib magnetic compass ua hauj lwm li cas?

Ib magnetic compass xwb vim hais tias lub ntiaj teb zoo li ib tug kev hlau cov giant nplaum, surrounded ntawm magnetic teb loj loj. Lub ntiaj teb yuav muaj ob magnetic rau tug uas pw ze qaum teb thiab sab qab teb tug. Magnetic teb ntawm lub ntiaj teb ua ib magnetized 'koob' hlau los yog hlau mus ua viav vias mus rau ib txoj hauj lwm qab teb qaum teb yog hais tias nws dai yog los ntawm ib cov xov, los yog nws tua yog los ntawm ib lub quav cab los yog daim ntoo floating nyob hauv ib lub tais dej.


Yog ua li cas yog cov magnetic compass?

Kom ntev dhau los ua cov xyoo 15th pua, mariners pom tias koob ntawm ib magnetic compass tsis taw tes kom yog yog rau ntiaj teb tseeb north. Columbus, xws li tau paub txog qhov no rau nws cov voyages thoob lub Atlantic hauv lub 1490s. Xwb, koob ua rau ib lub uas muaj tseeb qaum teb, thiab lub kaum ntse ntse ntawd nws txawv ntawm qhov chaw mus rau qhov chaw ntawm lub ntiaj teb nto. Qhov no txhais tau tias yog ib tug txawv magnetic variation rau ntau qhov hauv lub ntiaj teb. Cov variations tau tshawb xyuas rau ntawm ib xyoo pua naas ej 17th voyage los ntawm ntau tus paub txog thiab astronomer Edmond Halley. Nws txawm xav no lub sij hawm uas tus longitude ntawm ib lub nkoj yuav mus nrhiav tau ntawm lub compass variation, tiam sis qhov no proved tau tsis tseeb.


Cov teeb meem ntawm magnetic variation solved yog li cas?

Variations tsis txhawj navigators tam sim no vim yog kev taw qhia txog lub gyroscopic compass. Nws yog invented hauv 1908. Qhov no siv ib spinning gyroscope uas yuav taw qhov compass tsis tau rau sab qaum teb magnetic, tiam sis kom ntiaj teb sab qaum teb yeej muaj tseeb. Tus loj spinning gyroscope yog lub plawv ntawm lub gyrocompass. Thaum lub gyroscope no yog muaj teev raws spinning, nws tshua pointing huas, tsis hais lub nkoj suab heaving.

Hnub no, lub nkoj nyob ntiaj teb yuav saib nws txoj hauj lwm qhia kiag by means of ib lub teeb liab los ntawm ib tug satellite hauv orbit. Txawm li ntawd los, txhua navigators tseem muaj ib lub compass rau board thiab. Tracy Edwards, leej twg captained yacht leej hauv lub 1989-90 Whitbread hloov-tus-ntiaj teb Yacht haiv, siv cov Navsat (satellite navigation) thiab nrhiav tau nws twb muaj coob kev teeb meem uas nws siv lub magnetic compass xwb.
