Perpetuum mobile la Magnet?

Mararka qaarkood aad eegto bogga internetka ah, mar kale iyo mar ... Iyo, ka xumahay, u muuqataa sidii wan la iridda cusub. aragti waa in dayrka ma aha qarnigii XXI iyo XVI-th. Waa waagu ee xilligii kala guurka ee aadanaha laga soo saaray buugga soo saarka mishiinka. Laakiin dareen tani ma aha liibaanta sababta iyo sayniska, laakiin ka yara soo horjeeda. Haddii kale ma jiro lahaa mar kale iyo mar kale sara joogso, a motion Joogta magnet - fikradda ah, qaabdarro ee kaas oo si joogta ah oo qancisa la xaqiijiyay.

Fududeeyey inay salka fikradda ah dhaqdhaqaaq kasta oo weligiis ah waa: fudud ah (ama cajiib ah u adag - waxay ku xiran tahay male "hindisa" ah) farsamo, hal mar wadaa in lagu dhamystiro, aan xad lahayn ordaya. Laakiin sida wax qaab kale oo ka shaqeeya by tamarta amaahashada ka baxsan (taas oo loo baahan yahay sharciga ilaalinta tamarta si farsamaysan), waxaa soo baxday in mashiinka a motion Joogta shiday by tamarta ka meel.

qaabdarro The of this xaqiiqada ah, si kastaba ha ahaatee, ma aha sida iska cad sida awood la'aanta in ay kala qaybin dhowr ah oo ay eber. Haddii kale, sida aan kuu sharxi karaa xaqiiqada ah in qarniyo laba iyo badh iyo farsamo aan aqoonta lahayn iyo culimada bixiyey mashaariicda xad-dhaaf ah mashiinada mooshin weligeed ah, ka mid ah taas oo ahayd engine ee Magnet? Oo iyagu waxay noqon kartaa shaqo lahayn oo si joogto ah tijaabiyey aragti kaliya ma, laakiin sidoo kale experimentally! (At jeer waxaa u soo baxay in ay dhismaha prototypes.)

Ugu dambeyntii, in 1775 Academy Faransiis ee Sciences go'aansaday in mashaariicda mooshin hadda ka dib weligeed ah looma tixgelin doono.

"Age" go'aanka taariikhiga ah - saddex qarniyo. Ma waxaad u malaynaysaa Dadka ayaa kor u wised? Siidi by the "Casharrada" on site "Sidee si ay u dhisaan a magnet-dhaqaaq Joogta gacmahooda" - niskolechko.

Mid ka mid ah uu leeyahay oo kaliya in ay akhriyaan galay qoraaladii "alifay"! Halkan waxa aad iyo qalabka cusub ee foomka magnet neodymium, iyo guriga lagu beero "Aragti beerta midaysan", iyo ku dhawaaqidda dabcan dugsi aqoonta physics ku filan si ay u dhisaan mashiinka a motion weligeed ah. Laakiin halkan waa waxa dabeecad u, ku dhowaad oo dhan "alifay" ee tiro aad u badan oo uu ku feegaaraya sooco dhaleeceyn cadhooday oo ka mid ah "dacayadeed-saynisyahano" Beeniyey magnet-dhaqaaq weligeed ah "u gaar ah". Sida brand ay yihiin macallimiinta dugsiyada iyo jaamacadaha, "maskaxdooda urka" iyo "sasabtaan oo dhalinyarada!" Sida loo kala furfuraan ku dhowaad qaabeeya sida waraaqaha ee jawaabaha ka soo diray oo ku Academy of Sciences, machadyada iyo shaybaarada, peppered comments bile ay. Isla markiiba sheegay in akhristaha, waxaa soo baxday, in Europe iyo America a magnet-dhaqaaq Joogta hore u dhisay oo ordaya. (Ma aha hal tixraaca lagu kalsoonaan karo, si kastaba ha ahaatee, sabab qaar ka mid ah, lama siiyo.)

Ugu xumaa ee dhan, Cawaysimina idinkoo ku dacayadeed-cilmiyeed oo dhan si firfircoon uga faafin iyo clogs raadin matoorada. Sidaa darteed, marka la isku dayayo in la helo macluumaad si cilmiyeysan lagu kalsoonaan karo oo ku saabsan in aad had iyo jeer sawiri kartaa tamarta ka mid ah meel iyo ma kaa caawin doona haddii a magnet-dhaqaaq joogto u fudud, tusaale ahaan, si loo badbaadiyo tamarta, in khadadka ugu horeysay ee fuulid laguna soo iskibrin "Sweden aqoonsi ee waqtiga oo dhan." Oo waxa xitaa sadder - beenaalayaal iyo Bahdan, ururinta deeqaha loogu talagalay dhismaha ay qaabdarro waqtiyo badan si daacad ah la maleegey. Iyo, nasiib daro, waxay aaminsan yihiin ...
