Imisebenzi emininzi yokuhlola ngokuchanekileyo isengozini yokuphazamiseka kwemagnethi. Ii-gantries zesinyithi eziqhelekileyo zisebenza njengemithombo efihlakeleyo yeempazamo phantsi kweemeko zokusebenza ezinjalo. Ii-gantries zentsimbi kunye nesinyithi esityhidiweyo ziqhuba ngemagnethi. Nokuba zingenazo ii-magnetic field zangaphandle, ii-magnetic field ezibuthathaka eziveliswa ziimoto ezijikelezileyo, iintambo kunye nezixhobo ze-electromagnetic drive zinokufunxwa kwaye zidluliselwe ziifreyimu zesinyithi, nto leyo ebangela ukuphazamiseka kwe-magnetic field yendawo. Kwimisebenzi yokuhlola ejongene nee-magnetic fields, ukuphazamiseka okunjalo kwe-magnetic kuya kutshintsha ukufundwa kwe-sensor, kuphazamise i-optical detectors okanye kutshintshe imeko ye-magnetic yeesampulu zovavanyo, okukhokelela ngqo ekusileleni kokuhlolwa. Ipropati engeyiyo ye-magnetic ye-granite moving gantries ithintela ukuphazamiseka kwe-magnetic kwisakhelo esixhasayo, izenze zibe zizithuthi ezifanelekileyo kwiimeko zokuhlolwa ezijongene ne-magnetic conscious.
I-Granite yimbumba yeeminerali ze-silicate zendalo kwaye ayinazo izinto ze-ferromagnetic. Ayinakuba yimagnethi kwaye ayigcini magnethi eseleyo. Ngokungafaniyo neefreyimu zesinyithi, ii-granite gantries aziyi kutshintsha ukusasazwa kwe-magnetic field yokuqala, kwaye aziyi kudibanisa okanye ziphinde zitshintshe i-magnetic field phantsi kwe-changed okanye static weak magnetic fields ezijikeleze izixhobo. Xa oomatshini bokuhlola bexhotyiswe ngezinto ezinobuthathaka ezifana nee-magnetic sensors, ii-Hall probes kunye nee-magnetic force microscopes, i-gantry exhasayo ayizukungenisa ingxolo engaphezulu ye-magnetic. Imiqondiso eqokelelwe zii-probes ivela kuphela kwiisampulu ezivavanyiweyo endaweni yokuphazamiseka kwe-magnetic kwisakhelo. Olu phawu lwendalo olungelulo lwe-magnetic alufuni shielding coating eyongezelelweyo, ngoko ke akukho nciphiso yokusebenza ebangelwa kukuguga okanye ukuxobuka kwe-coating. Ihlala ingenamagnethi ngokuzinzileyo kwinkonzo yexesha elide.
Ezinye iinkqubo zokuhlolwa kwe-wafer kwishishini le-semiconductor zibeka ulawulo olungqongqo kwiintsimi zemagnethi ezikufutshane. Izakhiwo zesekethe ezichanekileyo ngaphakathi kwii-wafers zichaphazeleka kakhulu ziintsimi zemagnethi ezilahlekileyo, ezingachaphazeli kuphela ukufunyanwa kwesignali ngexesha lokuhlolwa, kodwa zinokonakalisa ii-microcircuits kwii-wafers kwiimeko ezinzima. Kwiiplatifomu zokuskena ezakhiwe ngee-gantries zesinyithi, iintsimi zemagnethi eziveliswa zii-motors ezithe nkqo kunye neentambo ze-servo zenza i-eddy currents kunye nee-magnetic loops kwizakhelo zesinyithi kwaye zandisa ukuguquguquka kwemagnethi yendawo. Ii-granite moving gantries azithathi nxaxheba ekwakhiweni kwe-magnetic loop kwaye zinceda ukugcina indawo ecocekileyo yemagnethi ngaphakathi kwendawo yokuhlolwa. Xa i-gantry iqhuba iimodyuli zokufumanisa ezibonakalayo okanye zemagnethi zokuskena okukhulu, intshukumo yesakhelo ayizukubangela ukuphazamiseka kwemagnethi kwangoko kwaye iqinisekisa idatha yokuhlolwa ehambelanayo kuyo yonke i-wafer.
Uvavanyo olungonakalisiyo lwezinto zemagnethi lolunye uhlobo oluxhomekeke kakhulu kwiziseko ezingezizo zemagnethi. Uvavanyo lokusebenza kweemagnethi ezisisigxina, iifilimu zemagnethi ezithambileyo kunye neesensors zemagnethi lufuna ukubanjwa ngokuchanekileyo kwemiqondiso yemagnethi ebuthathaka evela kwiisampuli. Ukuba ii-gantries eziqhuba ngemagnethi ziyasetyenziswa, ifreyimu iya kutsala imigca yemagnethi ekhutshwa ziisampuli, itshintshe imo yentsimi yemagnethi ejikeleze iisampuli kwaye ikhokelele ekufundweni okugqwethekileyo kwe-magnetic flux kunye nobunzulu bentsimi yemagnethi. Njengomzimba othwala umthwalo, ii-granite moving gantries aziphazamisi indlela yemigca yemagnethi. Idatha eqokelelwe zii-probes inokubonakalisa ngokwenene iipropati zemagnethi zangaphakathi zeesampuli. Ii-gantries ezihambayo ezinkulu zinokuthwala ii-probes ukuze zigqibezele ukuskena phezu kwemiphezulu emikhulu yemagnethi. Ngexesha lokuhlolwa okuqhubekayo kwe-dynamic, ifreyimu engeyiyo yemagnethi ayizukungenisa ukuphazamiseka kwemagnethi okuguquguqukayo njengoko islayidi ihamba.
Ukuhlolwa kwe-magnetic defect yezixhobo ze-elektroniki okubuthathaka kukwanceda kwiingenelo ezingezizo zemagnethi ze-granite gantries. Izixhobo ezincinci ezichanekileyo ezifana neefreyimu ze-chip lead, ii-miniature relay kunye nee-sensor magnetic cores zifuna ukuhlolwa ukuze kujongwe iingxaki zemagnethi ezifihlakeleyo ngexesha lokuveliswa. Izibonakaliso zemagnethi ezihambelana nezi mpazamo zincinci kakhulu, kwaye nayiphi na ingxolo engaphezulu yemagnethi iya kuntywilisela imiqondiso esebenzayo. I-metal gantries ikwavelisa i-tribo-magnetization kunye ne-eddy current effects ngexesha lokuhamba, nto leyo ephakamisa ingxolo yangasemva ngakumbi. I-granite moving gantries ayinazo iingxaki ezinjalo. Ifreyimu ayizukuvelisa imiqondiso eyongezelelweyo yemagnethi ngexesha lokuhamba okukhawulezayo kunye nokutshintsha kwe-start-stop, ngoko ke imiqondiso yemagnethi ebuthathaka ebuthathaka inokubanjwa ngokuthe chu zizixhobo zokufumanisa. 
Ezinye izixhobo zokuhlola ezidityanisiweyo ze-vacuum kunye ne-low-temperature nazo zikhetha izakhiwo ze-granite gantry ezingezizo ze-magnetic. Ezi zixhobo zinendawo encinci yangaphakathi enomngxuma enezixhobo zokuqhuba kunye nokuva ezicwangcisiweyo, nto leyo edala imeko-bume ye-electromagnetic eyinkimbinkimbi. Ukuvuleka kwe-magnetic kwizakhelo zesinyithi kuyatshintsha phantsi kobushushu obuphantsi, kwaye izinga lokuphazamiseka kwe-magnetic liyatshintsha-tshintsha ngokweqondo lobushushu, nto leyo ebangela ukungaqiniseki okungakumbi kwiziphumo zokuhlolwa. Iimpawu zomzimba ze-granite zihlala zizinzile kububanzi bobushushu, kwaye uphawu lwayo olungezizo ze-magnetic aluchaphazeleki bubushushu obuphantsi okanye kwiindawo ze-vacuum. Isakhelo se-gantry sinokudibaniswa ngaphakathi kwamagumbi e-vacuum ukuqhuba iindlela zokufumanisa ukuskena isampuli ngaphandle kokungenisa ukuphazamiseka kwe-magnetic okuguquguqukayo njengoko iimeko zendalo zitshintsha.
Ngaphezulu kwesakhelo esingengomagnetic, igranite ngokwayo inobulukhuni obuphezulu kunye nokuguquguquka okuphantsi, okwanelisa iimfuno ezichanekileyo ezimbini zokuhlolwa okubonakalayo kumagnetic. Izinto ezininzi ezingezizo zesinyithi ezingezizo zemagnethi azinabulukhuni obaneleyo, kwaye ii-gantry slides zidla ngokushukuma nge-elastiki ngexesha lokuhamba ngesantya esiphezulu kwaye zibangele iimpazamo zokubeka. Izakhiwo zegranite ezidibeneyo zibonelela ngobulukhuni obaneleyo kunye nokuguquguquka okuncinci ngexesha lokuhamba. Ngelixa zigcina indawo ecocekileyo kumagnetic, zigcina indawo yokunyakaza kwinqanaba le-micron, zidibanisa iimeko ezizinzileyo zemagnethi kunye nokuchaneka okuphezulu kokunyakaza. Ukwahlulwa kwemagnethi yendawo kunokusetyenziswa kwiindawo zesinyithi ezifana neereyile zesikhokelo kunye nezibophelelo. Ngokusebenzisana nomzimba oyintloko wegranite ongengomagnetic, ukuphazamiseka kwemagnethi iyonke kwenkqubo ye-gantry kunokugcinwa kwinqanaba eliphantsi kakhulu ukuhlangabezana neemfuno ezingqongqo zeemeko ezahlukeneyo zokuhlolwa okukhethekileyo.
