Хэрвээ та Коандын үзэгдэл болон туйлын цахилгаан хөдөлгүүрийн тухай ойлголтгүй бол энэхүү нийтлэл танд таалагдах болно.

Усны татах хүч

Виктор Шаубергерийг битгий Гүүглдээрэй

Гэрлээр наадаж тархиа гашилгацгаая

Таталцал гэж өөдгүй нөхөр шүү, зүгээр ажлаа хийхгүй юу?

Физикт итгэх нэг хэрэг, харин туршилт хийх нь бүр тэс өөр хэрэг шүү

Дуртай чиглэл – санах ой гэж байна уу?

Эргэлтийн хурд удааширч массын төв эхний байдалдаа эргэн орох хүртэл дээд орой нь доошоо эргэсэн чигээрээ л байна

Fine Wood Tippe-Top: spinning things often have surprising physics! This lathe worked version of the famous flip-over top is made of ebony and wood from the pink ivory tree. Friction with the mirror provides a torque that acts on the existing angular momentum of the top to flip it over. The top will stay flipped until the spin rate slows down enough to where its center of mass pulls it back to the resting position. ➡️ Follow the link in my profile for for details on where to get a tippe-top like this one and other amazing items featured here on @physicsfun #tippytop #tippetop #torque #angularmomentum #physics #physicstoy #flip #flipover #precession #spin #spinning #top #spinningtop #science #scienceisawesome

Magnetic Cube: a twisty Rubik’s Cube puzzle made from 27 dice and 208 neodymium magnets. This cube includes the scrambled states and solutions of the original 3×3 Rubik’s Cube but is held together only by magnets! The magnets, in this special configuration, lock the dice together with a satisfying click upon rotation. This beautiful cube was produced by Owen Lillywhite of magneticcube.com and is based on a gfixler design posted on instructables. ➡️ Follow the link in my profile for info on where to get a cube like this one and other amazing items featured here on @physicsfun #physics #physicsfun #magnets #neodymiummagnets #rubikscube #magneticcube #combinationpuzzle #dice #mathtoy #mathpuzzle #science #scienceisawesome

Homopolar Motor: a minimalist electric motor- battery, wire, and magnet. This type of motor does not need a commutator- the polarity of the electromagnetic coil does not need to reverse. The challenge with this design is balancing the coil to center on the battery as it rotates. A favorite DIY physics toy! ➡️ Follow the link in my profile for more info on how to make, or where to get, most of the amazing items featured here on @physicsfun #homopolar #electricity #electricmotor #physics #lorentzforce #physicstoy #coil #homopolarmotor #emf #neodymium #magnet #Bfield #electromagnet #science #scienceisawesome #electromagnetism #faraday

Маш энгийн цахилгаан хөдөлгүүр. Үүнтэй адилхан зүйл хийхийг хүсвэл танд зэс утас, соронз бас зай хэрэгтэй.

Electric Motor: in its simplest form!- coil, magnet, and battery. The wire of the coil has an insulating coating- and this coating is carefully scrapped off one side on each end. When current passes through the coil it becomes an electromagnet and the permanent magnet repels it making it spin- as it turns the currents goes on and off depending if the copper posts are in contact with the bare wire (current on) or the still insulated wire (current off). I have motors with fewer parts- but they operate on more complex principles. ➡️ Follow the link in my profile for information on where to get this motor and other amazing items featured here on @physicsfun #electromagnet #emf #physicsfun #electricmotor #physics #physicstoy #electriccurrent #science #worldssimplestmotor #windings #coils #electromagnetism #Bfield #ampereslaw #scienceisawesome #flux

Time's Up: inverse of the sandglass- tiny plastic beads are less dense than the water and thus ascend to the top of the container under the influence of a buoyant force in accordance with Archimedes' principle. This timer takes almost exactly 6 minutes to complete shown here at normal speed for the first half of this video, and the second half is condensed to 24 seconds in time-lapse. ➡️ Follow the link in my profile for information on where to buy timers like this and other amazing items featured here on @physicsfun #sandtimer #hourglass #buoyancy #bouyantforce #archimedes #archimedesprinciple #physics #physicstoy #liquidmotion #fluiddynamics #science #scienceisawesome #timelapse

Tea-Light Floating Engine: a candle powered super simple steam engine. The engine is just a coil of copper tubing filled with water. Steam builds up pushing water out with an explosive jet- which then results in a vacuum in the coil which pulls more water in to repeat the process. The water expulsion is in the form of jet directed out the end of the tube whereas the refill comes back in to the tube from a larger range of angles- so on balance the engine moves opposite to the direction of the jets. ➡️ Follow the link in my profile for info on where to get this simple engine kit and other amazing items featured here on @physicsfun #engine #physics #thermodynamics #physicstoy #steamengine #phasechange #poppopboat #science #tealight #scienceisawesome #candle #heatengine

Коандагийн үзэгдэл

Уг үзэгдлийг тасалгааны таазанд хуримтлагдсан агаарын урсгалыг хөдөлгөөнд оруулах сплит-системд ашигладаг буюу тасалгааны агаар солилцоог сайжруулахад хэрэглэдэг байна.
