Ke koho ʻana i nā mea paʻa paʻa a me ka hoʻohana ʻana i nā mea hoʻohana ʻana i nā mea ʻike maka

Koho oMea Magnet Mauno ka mea ʻike maka ʻulaʻula

Ma ka ʻōlelo maʻamau, pono e noʻonoʻo ke koho ʻana i ka magnet no ka sensor hoʻololi ʻana i nā ʻano noi like ʻole, e like me ka mahana hana, ka hopena demagnetization, ka ikaika o ke kahua magnetic, nā ʻano kūlohelohe, ka neʻe a me ka noi. ʻO nā hiʻohiʻona nui no nā ʻano mea kaulana loa o nā mea magnetic paʻakikī e like me kēia:

Ka Honua Neodymium-Iron-Boron Magnet

1. Nā huahana ikehu kiʻekiʻe loa

2. Kiʻekiʻe loa remanance a coercivity

3. Kumukuai haahaa

4. ʻOi aku ka ikaika mechanical ma mua o ka magnet Samarium Cobalt

Kakaʻikahi Samarium Cobalt Magnet

1. Huahana ikehu magnetic kiʻekiʻe

2. He kūpono no nā noi hana kiʻekiʻe

3. Kū'ē demagnetization kiʻekiʻe

4. Paʻa wela maikaʻi

5. Kiʻekiʻe corrosion kū'ē

6. ʻO ka magnet pipiʻi loa

7. Hoʻohana ʻia i ka mahana a hiki i 350 ° C

Alnico Magnet

1. ʻOi aku ke kumu kūʻai ma mua o nā mea magnet honua

2. ʻO ka mahana hana kiʻekiʻe loa i 550 ℃

3. ʻO ka helu wela liʻiliʻi

4. Haʻahaʻa coercivity

5. High koena induction

Ferrite a i ʻole Ceramic Magnet

1. Nawaliwali

2. Maika'i loa ma waena o kēlā mau mea magnet eha

3. Ke hana nei i loko o 300 ° C

4. Pono ka wili ʻana e hoʻokō i nā tolerances koʻikoʻi

5. Kiʻekiʻe corrosion kū'ē

ʻO nā noi nui o ka mīkini hoʻololi Magnetic

1. Hoʻohana ʻia ka mea ʻike wikiwiki ma ke kaʻamākia neodymium cylindrical.

2. He mea kū hoʻokahi ka hoʻololi o ka ʻohe magnetic i ka ʻōnaehana hoʻoili wai. Hiki ke hoʻokomo pololei ʻia ke kuapo magnetic ma ka poloka cylinder. Ke piston me kaSmCo magnet apoe neʻe ana i ke kūlana o ka mea hoʻololi magnetic, ua huki ʻia nā ʻohe ʻelua i loko o ka hoʻololi maʻemaʻe ma lalo o ka hana a ke kahua magnetic o ke apo magnetic e hoʻouna i kahi hōʻailona. Ke neʻe aku ka piston, haʻalele ka puna puna alelo i ke kahua magnetic, wehe koke ka pilina a ʻoki ʻia ka hōʻailona. Ma kēia ala, hiki ke ʻike maʻalahi ke kūlana o ka piston cylinder.

3. ʻO kekahi ʻano hoʻololi hoʻololi magnetic hou, ʻo ia ka mea hoʻololi hoʻololi magnetic, ʻike ʻia hoʻi ʻo ka hoʻololi hoʻokomo magnetic. Loaʻa iā ia kahi pūpū plastik, kahi e hoʻopili ai i ke kī ʻohe i loko o ka pūpū ʻeleʻele a alakaʻi i waho o ka uea. Hoʻopaʻa ʻia ka hapa ʻē aʻe o ka pūpū plastik me kahi magnet paʻa ma kekahi ʻaoʻao. Kemagnet paakikikokoke i ke kuapo me ka uwea, hoʻouna ia i ka hōʻailona hoʻololi. ʻO 10mm ka mamao hōʻailona maʻamau. Hoʻohana nui ʻia kēia huahana i nā puka anti-theft, nā puka hale, nā mea paʻi, nā mīkini fax, nā kelepona, a me nā mea uila a me nā lako.

4. Ke hoʻohana nei ka puka friji i ke kī ʻohe no ka ʻike pani pani puka. Hoʻokomo ʻia ka magnet paʻa ma ka puka a ua hoʻopili ʻia ka sensor reed magnetic i kahi kiʻi paʻa i hūnā ʻia ma hope o ka paia o waho o ka pahu hau. Ke wehe ʻia ka puka, ʻaʻole hiki i ka mea ʻike ʻohe ke ʻike i ke kahua magnetic, e hoʻomālamalama ʻia ke kukui LED. Ke pani ʻia ka puka, ʻike ka sensor magnetic i ke kahua magnetic kūpono a hele i waho ke LED. I loko o kēia noi, loaʻa i ka microcontroller i loko o ka hāmeʻa kahi hōʻailona mai ka sensor reed, a laila hoʻāla a hoʻopau paha ka mana hoʻokele i ka LED.
