Buru n'uche na nke a bụ ọnọdụ dị mfe na ọ nwere ike ọ gaghị anọchi anya nkesa magnetik n'ọnọdụ ndị siri ike karị. Ọ bụrụ na ndọta abụghị otu, ma ọ bụ ọ bụrụ na akụkụ cylinder ahụ esighị oke karịa dayameta ya, mgbako ahụ ga-adị mgbagwoju anya ma nwee ike ịchọ usoro ọnụọgụ ma ọ bụ nyocha.

Maka nsonaazụ ziri ezi karị, ị nwere ike ịchọ iji ụzọ dị elu dịka ihe atụ ọnụọgụgụ site na iji nyocha ihe nwere njedebe ma ọ bụ ụzọ nyocha nke na-atụle ihe onwunwe magnetik nke ihe ahụ na nkesa magnetik n'ezie n'ime silinda ahụ.

Okwu ahụ bụ́ na ebe ndọta ahụ efu dị n'ime silinda nwere ike ịbụ nghọtahie ma ọ bụ ime ka ọ dị mfe. N'ozuzu, ebe ndọta ahụ dị n'ime silinda magnetized otu otu abụghị efu. Agbanyeghị, dabere na ọnọdụ na echiche ndị a kapịrị ọnụ, e nwere ọnọdụ ebe ebe ebe ndọta ahụ dị n'ime silinda nwere ike ịdị obere ma ọ bụ gosipụta ụfọdụ ihe onwunwe nke nwere ike ime ka o yie ka ebe ahụ enweghị ihe ọ bụla.

Lee ihe ole na ole nwere ike ime ka mmadụ chee na ebe ndọta ahụ efughị ​​n'ime silinda:

1. Ọta
2. Ịmegharị otu Igwe

Ọ dị mkpa ịmara na ebe ndọta dị n'ime magnet cylindrical ga-adabere n'ọtụtụ ihe, gụnyere nkesa magnetization, ọdịdị magnet ahụ, ihe onwunwe ya, na mmetụta mpụga dịka ebe ndọta dị nso ma ọ bụ ihe nchebe. N'ozuzu, enwere ike ịgbakọ ma mee ka ike ebe ndọta dị ka ihe ndị a si dị, mana o yighị ka ebe ahụ ga-adị kpọmkwem efu n'ime silinda magnetized otu.

Ee, enwere ike ịnwe oghere ndọta n'ime cylinder oghere, ma ọ bụrụhaala na cylinder nwere ụdị ndọta. Ọnụnọ na njirimara nke oghere ndọta n'ime cylinder oghere na-adabere n'ihe ndị dị ka usoro magnetization, ihe onwunwe, na geometry nke cylinder.

Ọdụ magnet dị n'ime na n'èzí magnet dị n'ime ụlọ na-adabere n'ọtụtụ ihe, gụnyere ụkpụrụ magnetization, ihe onwunwe ya, na ọdịdị nke silinda ahụ. Ka anyị tụlee ụfọdụ ọnọdụ:

2. Silinda Magnetized Radially
3. Silinda oghere demagnetized
4. Silinda mkpuchi ndọta

Nkọwa ndị a dị mfe nghọta, omume nke ubi magnet nwere ike ịdị mgbagwoju anya dabere na ọnọdụ na echiche ndị a kapịrị ọnụ. N'ọrụ, a na-enyocha nkesa ubi magnet site na iji ụdị mgbakọ na mwepụ ma ọ bụ ngwanrọ simulation nke na-eburu n'uche njirimara zuru ezu nke magnet na gburugburu ya.
