ʻAʻole hiki i nā poʻe he nui ke hoʻokaʻawale ma waena o ka mōʻī kuʻi a me ka mōʻī kuʻi magnetic ma ka mīkini ana ʻike.I kēia lā e kamaʻilio mākou e pili ana i ka ʻokoʻa ma waena o lākou.
ʻO ka unahi kuʻikuʻi he mea ʻike i hana ʻia e ke kumu o ka hoʻopili māmā a me ka diffraction.I ka wā e hoʻopaʻa ʻia ai ʻelua mau pahu me ka pitch hoʻokahi, a hana nā laina i kahi kihi liʻiliʻi i ka manawa like, a laila ma lalo o ka hoʻomālamalama ʻana o ke kukui like, hiki ke ʻike ʻia nā kaha māmā a me nā kaha ʻeleʻele ma ke ala pololei o nā laina.Kapa ʻia ʻo ia ʻo Moiré fringes, no laila ʻo Moiré fringes ka hopena i hui ʻia o ka diffraction a me ka interference o ka mālamalama.Ke hoʻoneʻe ʻia ka pahu kuʻi e kahi pitch liʻiliʻi, hoʻoneʻe ʻia nā kihi moiré e hoʻokahi pitch fringe.Ma kēia ala, hiki iā mākou ke ana i ka laulā o nā ʻāpana moiré i maʻalahi ma mua o ka laulā o nā laina grating.Eia kekahi, no ka mea, ua haku ʻia kēlā me kēia laʻi moire i nā ʻāpana o nā laina kuʻikuʻi he nui, ke loaʻa ka hewa o kekahi o nā laina (ka ʻokoʻa like ʻole a i ʻole ke kuʻekuʻe), ʻo kēia laina kuhi hewa a me ka laina grating ʻē aʻe. .Eia nō naʻe, ua haku ʻia kahi laʻi moiré me nā ʻāpana laina he nui.No laila, he liʻiliʻi loa ka hopena o ka hoʻololi ʻana o ke kūlana o kahi hui laina i ka ʻaoʻao moiré, no laila hiki ke hoʻohana ʻia ka moire fringe e hoʻonui a me ka hopena maʻamau.
ʻO ka pālākiō magnetic kahi mea ʻike i hana ʻia me ka hoʻohana ʻana i ke kumu o nā pole magnetic.ʻO kona lula kumu he ʻano kila magnetized.Hoʻokaʻawale ʻia kona mau pou S a me N ma ke kaula kila, a heluhelu ke poʻo heluhelu i nā loli o nā pou S a me N e helu.
Hoʻopilikia nui ʻia ka pānaʻi grating e ka mahana, a ʻo ka hoʻohana maʻamau ma lalo o 40 degere Celsius.
Hoʻopili maʻalahi ʻia nā unahi magnetic wehe e nā māla magnetic, akā ʻaʻohe pilikia i nā unahi magnetic paʻa, akā ʻoi aku ka nui o ke kumukūʻai.
