Mphamvu ya maginito a solenoid lapansi. electromagnets

Mosakayikira, mwana onse ankakonda kusewera ndi maginito lapansi. Pezani maginito okhazikika anali lophweka: pamafunika kupeza ndime akale, kuchotsa izo kwa phokoso kubereka wokamba ndipo pambuyo yosavuta "vandalnyh kanthu," kutuluka mphete maginito ake. N'zosadabwitsa kuti ambiri mayeso zinachitikadi ndi filings zitsulo ndi pepala. Utuchi anaika mikwingwirima - pamodzi mizere ya mphamvu kumunda.

Okonza magetsi ndi zambiri kwambiri kuposa okhazikika ndi electromagnets. maginito, kukula kwa amene mwachindunji zokhudzana ndi phindu panopa pa njira zamakono za sayansi amadziwika kuti pamene magetsi inawadutsa umayenda mwa wochititsa, kuzungulira otsiriza analenga.

Okayikira mwina kubwereza kuyesera yosavuta Oersted, pamene kampasi aikidwa pafupi ndi wochititsa molunjika. Muvi udzakupangeni ku malo osiyanasiyana kumpoto kwa dziko (perpendicular kwa waya). kuchimwa malangizo zingadziŵike ntchito dzanja lake lamanja ulamuliro: ikani dzanja lanu lamanja kanjedza pansi, ikufanana ndi wochititsa lapansi. 4 zala ayenera akulozera malangizo a pano. Ndiye wopindidwa madigiri 90 chala chachikulu zikusonyeza malangizo a muvi kuchimwa. Padziko waya molunjika maginito ali maonekedwe a yamphamvu ndi waya pakati. Koma mavuto mizere kupanga mphete.

Mu magetsi anati mphamvu ya maginito ntchito makamaka coils lapansi. Mukhoza kumva mawu akuti "maginito ya solenoid lapansi." Tiyerekeze ndi msomali wamba, ndi waya woonda kwayekha. Imatulutsa kumulowetsa waya pa msomali, ife kupeza solenoid. Pankhaniyi, msomali zimakhudza maginito ya solenoid, koma ichi ndi mutu nkhani ina kwathunthu. Nkofunika kuti umvetse kwenikweni tanthauzo la mawu. Ngati inu tsopano kulumikiza koyilo ku gwero mphamvu, ndiye kuzungulira maginito kutero.

solenoid maginito mphamvu ndi mwachindunji njila kwa mtengo wa inductance ndi m'bwalo la m'kupita panopa kudzera coils lapansi. Nawonso inductance zimadalira lalikulu chiwerengero cha motsatana. Kuyenera ofalitsidwa kumulowetsa kapangidwe: zingakhale mulandu wosavuta wosanjikiza imodzi motsatana komanso dongosolo multilayer kumene malangizo panopa mu ankasinthana wa kanthu kukonza amapereka mphamvu zonse. Solenoids ntchito trams madera kudula njira, etc. contactors.

Mphamvu ya maginito a solenoid ndi mphete anakafika ku malekezero a kumulowetsa ndi a ena. Mkati mzere mphamvu mulibe mawu koyilo, ndipo amafalitsidwa mu dielectric sing'anga kapena pakati conductive. Chotsatira: a solenoid munda wa polarity. Mizere kubwera kuchokera kumpoto maginito kumpoto, ndi kubwerera kum'mwera. Predictably, mphamvu ya maginito a solenoid chimadalira pa polarity wa gwero panopa olumikizidwa kwa malekezero a mawaya. The katundu maginito ya solenoid ndi pafupi zofanana monga maginito okhazikika. Ichi chizathandiza ntchito solenoid monga solenoid lapansi. Kupanga cranes Tingaone, imene m'malo mbedza anaika electromagnet pagalimoto. Izi ndi "m'chimwene wamkulu" wa solenoid wa - kumulowetsa pa pakati. The peculiarity wa electromagnets ndi kuti katundu maginito unalipo pamene panopa umayenda mwa windings wa.

Kuwonjezera solenoids Mankhwalawa amagwiritsidwa ntchito toroids. Awa ndi amodzi waya coils koma chilonda pa maziko maginito ya mawonekedwe chonse. Motero, maginito ya solenoid ndi toroid osiyana. Mbali yaikulu ndiyakuti mizere ya mphamvu za kuthengo maginito amafalitsidwa pa tsinde-koyilo m'kati mwa dera maginito, osati kunja, monga zinachitikira solenoid lapansi. Zonsezi ndi umboni kwa dzuwa apamwamba a coils pa mphete magnetically zakuthupi. Impact: The tiransifoma toroidal odalirika ndipo ndi zomvetsa poyerekeza ndi anzawo nthawi zonse.
