He nui nā hana nānā pono e palupalu i ka hoʻopilikia magnetic. Hana nā gantries metala maʻamau ma ke ʻano he kumu hewa huna ma lalo o ia mau kūlana hana. He alakaʻi magnetic nā gantries kila a me ka hao i hoʻolei ʻia. ʻOiai me ka ʻole o nā kahua magnetic waho, hiki ke omo ʻia a hoʻouna ʻia nā kahua magnetic nāwaliwali i hana ʻia e nā motika a puni, nā kaula a me nā ʻāpana hoʻokele electromagnetic e nā mōlina metala, e hopena ana i ka hoʻopilikia ʻana o ke kahua magnetic kūloko. No nā hana nānā i pili i nā kahua magnetic, e hoʻopilikia kēlā hoʻopilikia magnetic i nā heluhelu sensor, e hoʻopilikia i nā mea ʻike optical a hoʻololi paha i ke kūlana magnetic o nā laʻana hoʻāʻo, e alakaʻi pololei ana i ka hāʻule ʻana o ka nānā ʻana. ʻO ka waiwai non-magnetic kūlohelohe o nā gantries granite e pale aku i ka hoʻopilikia magnetic mai ke kiʻikuhi kākoʻo, e lilo ana iā lākou i mau mea lawe kūpono no nā hiʻohiʻona nānā magnetic sensitive.
He hui ʻia ka Granite o nā minelala silicate kūlohelohe a ʻaʻohe ona mea ferromagnetic. ʻAʻole hiki ke magnetized a ʻaʻohe koena magnetism. ʻAʻole e like me nā mōlina metala, ʻaʻole e hoʻololi nā gantries granite i ka hoʻolaha ʻana o ke kahua magnetic mua, ʻaʻole hoʻi e hui pū a hoʻohuli paha i nā kahua magnetic ma lalo o nā kahua magnetic nāwaliwali a static a puni nā lako. Ke hoʻolako ʻia nā mīkini nānā me nā ʻāpana koʻikoʻi e like me nā sensor magnetic, nā Hall probes a me nā microscopes ikaika magnetic, ʻaʻole e hoʻokomo ka gantry kākoʻo i ka walaʻau magnetic keu. Loaʻa nā hōʻailona i hōʻiliʻili ʻia e nā probes mai nā laʻana i hoʻāʻo ʻia ma kahi o ka hoʻopilikia magnetic mai ka mōlina. ʻAʻole pono kēia hiʻohiʻona kūlohelohe non-magnetic i ka uhi pale hou, no laila ʻaʻohe hōʻino hana i hoʻokumu ʻia e ka ʻelemakule ʻana o ka uhi a i ʻole ka ʻili ʻana. Noho paʻa ia ʻaʻole magnetic ma luna o ka lawelawe lōʻihi.
Hoʻokau kekahi mau kaʻina hana nānā wafer i ka ʻoihana semiconductor i ka mana koʻikoʻi ma luna o nā kahua magnetic ambient. ʻO nā ʻano kaapuni pololei i loko o nā wafers he mea maʻalahi loa ia i nā kahua magnetic hele hewa, ʻaʻole wale ia e hoʻopilikia i ka loaʻa ʻana o ka hōʻailona i ka wā o ka nānā ʻana, akā hiki ke hōʻino i nā microcircuits ma nā wafers i nā hihia koʻikoʻi. No nā kahua scan i kūkulu ʻia me nā gantries metala, nā kahua magnetic i hana ʻia e nā motika linear a me nā kaula servo e hana i nā kahe eddy a me nā loop magnetic ma nā mōlina metala a hoʻonui i nā fluctuations magnetic kūloko. ʻAʻole komo nā gantries neʻe Granite i ka hoʻokumu ʻana o ka loop magnetic a kōkua i ka mālama ʻana i kahi kaiapuni magnetic maʻemaʻe i loko o ka wahi nānā. Ke hoʻokele ka gantry i nā modules ʻike optical a magnetic paha no ka scanning ākea nui, ʻaʻole e hoʻoulu koke ka neʻe ʻana o ka mōlina i ka haunaele magnetic a hōʻoia i ka ʻikepili nānā kūlike ma ka wafer holoʻokoʻa.
ʻO ka hoʻāʻo ʻana i nā mea makeneka ʻaʻole luku ʻia kekahi hiʻohiʻona e hilinaʻi nui ʻia ana ma nā kumu makeneka ʻole. Pono ka hoʻāʻo hana o nā makeneka mau loa, nā kiʻiʻoniʻoni makeneka palupalu a me nā mea ʻike makeneka i ka hopu pololei ʻana i nā hōʻailona makeneka palupalu mai nā laʻana. Inā hoʻohana ʻia nā gantries alakaʻi makeneka, e huki ka mōlina i nā laina makeneka i hoʻopuka ʻia e nā laʻana, e hoʻololi i ke ʻano o ke kahua makeneka a puni nā laʻana a alakaʻi i nā heluhelu hoʻololi ʻia o ka flux makeneka a me ka ikaika o ke kahua makeneka. Ma ke ʻano he kino lawe ukana, ʻaʻole e hoʻopilikia nā gantries neʻe granite i ke ala o nā laina makeneka. Hiki i ka ʻikepili i hōʻiliʻili ʻia e nā probes ke hōʻike maoli i nā waiwai makeneka kūloko o nā laʻana. Hiki i nā gantries neʻe ākea nui ke lawe i nā probes e hoʻopau i ka scan ma luna o nā ʻili makeneka nui. I ka wā o ka nānā ʻana i ka dynamic, ʻaʻole e hoʻokomo ka mōlina non-magnetic i ka hoʻopilikia makeneka dynamic i ka neʻe ʻana o ka slide.
Loaʻa pū kekahi pōmaikaʻi o ka nānā ʻana i nā hemahema magnetic nāwaliwali o nā ʻāpana uila mai nā pono non-magnetic o nā gantries granite. Pono nā ʻāpana kikoʻī liʻiliʻi e like me nā kiʻi alakaʻi chip, nā relays miniature a me nā ʻiole magnetic sensor e nānā no nā anomalies magnetic maalea i ka wā o ka hana ʻana. He palupalu loa nā hōʻailona magnetic e pili ana i kēlā mau hemahema, a ʻo kekahi walaʻau magnetic keu e hoʻoluliluli i nā hōʻailona kūpono. Hoʻopuka pū nā gantries metala i nā hopena tribo-magnetization a me nā hopena eddy current i ka wā o ka neʻe ʻana, e hoʻonui hou ana i ka walaʻau hope. ʻAʻohe pilikia o nā gantries neʻe Granite. ʻAʻole e hoʻopuka ka mōlina i nā hōʻailona magnetic keu i ka wā o ka neʻe reciprocating wikiwiki a me ka hoʻololi hoʻomaka-hoʻōki, no laila hiki ke hopu mau ʻia nā hōʻailona magnetic hemahema palupalu e nā lako ʻike. 
Makemake pū kekahi mau lako hana nānā vacuum a me nā mea hana nānā haʻahaʻa i hoʻohui ʻia i nā ʻano gantry granite non-magnetic. Loaʻa i kēlā mau lako kahi hakahaka kūloko i kaupalena ʻia me nā ʻāpana hoʻokele a me nā ʻike i hoʻonohonoho pono ʻia, e hana ana i kahi ʻano electromagnetic paʻakikī. Hoʻololi ka permeability magnetic o nā kiʻi metala ma lalo o ka mahana haʻahaʻa, a ʻo ke kiʻekiʻe o ka hoʻopilikia magnetic e loli me ka mahana, e lawe mai ana i ka maopopo ʻole i nā hopena nānā. Noho paʻa nā waiwai kino o ka granite ma luna o kahi ākea ākea o ka mahana, a ʻaʻole i hoʻopilikia ʻia kona ʻano non-magnetic e nā wahi mahana haʻahaʻa a i ʻole ka vacuum. Hiki ke hoʻohui ʻia ka gantry frame i loko o nā keʻena vacuum e hoʻokele i nā mīkini ʻike no ka scanning laʻana me ka ʻole o ka hoʻokomo ʻana i ka hoʻopilikia magnetic loli i ka wā e loli ai nā kūlana o ke kaiapuni.
Ma luna o ke kiʻikuhi non-magnetic, hōʻike ka granite ponoʻī i ke kūpaʻa kiʻekiʻe a me ka deformation haʻahaʻa, e hoʻokō ana i nā koi kikoʻī pālua no ka nānā ʻana i ka magnetic sensitive. ʻAʻole lawa ka paʻakikī o nā mea non-metallic non-magnetic, a ʻo nā paheʻe gantry e lūlū elastically i ka wā o ka neʻe wikiwiki a hana i nā hewa kūlana. Hāʻawi nā ʻano granite i hoʻohui ʻia i ka paʻakikī kūpono a me ka deformation liʻiliʻi i ka wā o ka neʻe ʻana. ʻOiai e mālama ana i kahi kaiapuni maʻemaʻe magnetic, mālama lākou i ke kūlana neʻe micron-level, e hoʻohui ana i nā kūlana magnetic paʻa a me ka pololei neʻe kiʻekiʻe. Hiki ke hoʻopili ʻia ka hoʻokaʻawale magnetic kūloko i nā ʻāpana metala e like me nā ala alakaʻi a me nā mea paʻa. Ma ka hana pū ʻana me ke kino nui granite non-magnetic, hiki ke mālama ʻia ka hoʻopilikia magnetic holoʻokoʻa o ka ʻōnaehana gantry holoʻokoʻa ma kahi pae haʻahaʻa loa e hoʻokō i nā koi koʻikoʻi o nā hiʻohiʻona nānā kūikawā like ʻole.
