Hans Christian Ørsted, Ørsted kuj sau Oersted, (yug Lub Yim Hli 14, 1777, Rudkøbing, Denmark-tuag Lub Peb Hlis 9, 1851, Copenhagen), Danish physicist thiab chemist uas nrhiav tau uas hluav taws xob tam sim no hauv ib hlau yuav deflect ib tug magnetized compass koob, ib qho tshwm sim qhov tseem ceeb ntawm uas tau pom sai sai thiab qhov twg …
Oersted qhov kev tshawb pom ua li cas cuam tshuam rau keeb kwm ntawm kev tshawb fawb?
Nws qhov kev tshawb pom tsis txaus ntseeg tau ua rau txoj hauv kev rau tag nrho ceg tshiab ntawm kev tshawb fawb: electromagnetics. Cov hlau nplaum tsim los ntawm hluav taws xob hu ua electromagnetism. Christian Oersted ua qhov kev tshawb pom tseem ceeb uas hluav taws xob tam sim no tsim cov hlau nplaum.
Oersted nrhiav kev sib raug zoo ntawm hluav taws xob thiab hlau nplaum li cas?
Xyoo 1820, Oersted tau tshawb pom los ntawm kev sib tsoo uas hluav taws xob tam sim no tsim cov hlau nplaumUa ntej ntawd, cov kws tshawb fawb xav tias hluav taws xob thiab hlau nplaum tsis cuam tshuam. Oersted kuj siv lub compass los nrhiav cov kev taw qhia ntawm magnetic teb nyob ib ncig ntawm ib tug hlau nqa tam sim no.
Kev siv lub neej tiag tiag ntawm electromagnetism yog dab tsi?
Electromagnets tau dav siv los ua cov khoom ntawm lwm cov khoom siv hluav taws xob, xws li motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic Cov khoom sib cais.
Kev siv hluav taws xob yog dab tsi?
Kev siv thev naus laus zis ntawm electromagnetism suav nrog xov tooj ntawm tes, MRI scanners, tsheb ciav hlau maglev, TVs, video thiab audio tapes, cov ntaub ntawv khaws cia, hais lus, microphones, thiab lub tswb nrov.
