Perpetuum Mobile pamwe magnets a?

Dzimwe nguva iwe tarisa pa-web page iri, zvakare uye zvakare ... Uye, urombo, anotarisa sezvinoita gwai itsva pasuwo. Pfungwa iri kuti pachivanze haasi XXI remakore uye XVI-ndipo. Ndicho mambakwedza nguva vanhu achichinja kubva Chinyorwa kuti muchina kugadzirwa. Asi kunzwa ichi hachisi yakunda chikonzero nesayenzi, asi chokwadi. Zvimwe paisazova simuka zvakare uye zvakare, vavate inofamba magnets A - pfungwa, kusava nomusoro rakanga kakawanda uye zvinogutsa nekusimba.

Zvakawanda kune mujinga pfungwa ipi nokusingaperi inofamba iri: nyore (kana kusimba kuoma - kunobva zvokufungidzira "muvambi") mashandiro, kamwe kutanga, achimhanya nokusingaperi. Asi sezvo mamwe mashandiro anoita nokuda nokukwereta simba kubva kunze (ndiko kunodiwa nomurayiro kuchengetedza kwakaita zvokuimba simba), zvinoitika kuti nokusingaperi inofamba muchina dzakawedzerwa nemashoko simba kubva asiko.

Kusava nomusoro ichi Zvisinei, chokwadi, iri kwete pachena sezvo nekusagona dzekuputsa pakuwanda razero. Zvikasadaro, tingagona sei kutsanangura chokwadi kuti maviri nehafu emakore navapfuri vesimbi vasina kudzidza uye nyanzvi vakapa zvakawanda zvirongwa isingaperi inofamba michina, pakati chakanga injini kuti magnets a? Uye havagoni kuva basa kusingaperi nguva akaratidza kwete hunonzi chete asiwo experimentally! (Dzimwe nguva akakwira pakuvaka prototypes.)

Pakupedzisira, muna 1775 yeFrench Academy of Sciences akasarudza kuti kubvira nokusingaperi inofamba muzvirongwa haazorambi kunzi.

"Age" chisarudzo ichi enhoroondo - matatu emakore. Unofunga vanhu wised kumusoro? Kutonga nezvinooneka "Tutorials" panzvimbo "How kuvaka nokusingaperi inofamba magnets a nemaoko" - niskolechko.

Mumwe ane chete kuverenga kupinda zvakanyorwa "vanotanga"! Pano iwe uye zvinhu zvitsva muchimiro neodymium magnets a, uye musha-akura "rakabatana munda pfungwa", uye kuziviswa kosi kuchikoro wefizikisi zivo yakakwana kuvaka nokusingaperi inofamba muchina. Asi pano pane chii maitire: anenge ose "vanotanga" imwe huru yakawanda scribbling ake kupedzera hasha kutsoropodzwa "ekunyebera masayendisiti" vanoramba "rakasiyana" nokusingaperi inofamba magnets a. Sezvo muchiso vari vadzidzisi zvikoro uye mumayunivhesiti, "clogging uropi" uye "kanganisa pfungwa mwana!" Sei gujunura anenge akaumbwa sezvo tsamba mhinduro akatuma Academy of Sciences, ne mumarabhoritari, peppered bile zvavanotaura. Pakarepo vakaudza muverengi: zvinoitika, muna Europe uye America nokusingaperi inofamba magnets a kare kuvakwa uye kumhanya. (Kwete imwe yakavimbika reference, zvisinei, nokuti vamwe chikonzero, hakuna kupiwa.)

Kupfuura zvose, zviri ekunyebera yesayenzi yose maturo achishingaira inoparadzirwa uye clogs kunotsvaga injini. Naizvozvo, kana kutsvaka mashoko nesayenzi akavimbika pamusoro kana unogona uchiswedera simba pasina uye haangazvidembi kubatsira kana munhu nyore isingaperi inofamba magnets a Somuenzaniso, kuponesa simba, ari akarongwa issuance kukwira nokuzvikudza yokutanga "harimboonekwi geniuses nguva dzose." Uye chii kunyange sadder - nhema uye nevanyengeri, kuunganidza mari yezvipo kuti kuvakwa kwayo upenzi nguva kupfuura zvinhu zvisiri zvechokwadi. Uye, zvinosuruvarisa Vanodavira ...
