B) gburugburu magnetik cylindrical nwere ike ịdị mgbagwoju anya, dabere na nkesa magnetization n'ime cylinder. N'ebe a, m ga-akọwapụta ikpe dị mfe ebe anyị nwere cylinder magnetized n'otu n'otu yana axis magnetization ya kwekọrọ na axis cylinder. A na-akpọkarị nke a dị ka "Silinda magnetized ogologo oge."

B) n'èzí a uniformly magnetized cylinder tinyere ya Central axis nwere ike approximated site na iji usoro maka ubi n'ime a solenoid. Mkpebi a na-eche na cylinder dị ogologo karịa dayameta ya. Usoro bụ:

$�=�\cdot �$

B=μ⋅M

Ebe:

Enwere ike gbakọọ M dị ka:

$�=\; mkpokọta�cylinder$

M = Vcylinder Mtotal

Ebe:

• 
  $�\; mkpokọta$

  Mtotal bụ ngụkọta oge ndọta nke cylinder (na A m²).

  Vcylinder bụ olu cylinder (na m³).

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 karịa, ịnwere ike iji ụzọ dị elu dị ka ịme anwansị ọnụọgụgụ site na iji nyocha mmechi ma ọ bụ ụzọ nyocha nke na-atụle njirimara magnetik nke ihe ahụ yana nkesa magnetik n'ezie n'ime cylinder.

Nkwupụta na oghere magnetik bụ efu n'ime cylinder nwere ike ịbụ nghọtahie ma ọ bụ imebiga ihe ókè. N'ozuzu, oghere magnetik dị n'ime cylinder magnetized edo edo abụghị efu. Otú ọ dị, dabere na ọnọdụ na echiche ndị a kapịrị ọnụ, e nwere ebe ebe magnetik dị n'ime cylinder nwere ike ghara ịdị ike ma ọ bụ gosipụta ụfọdụ ihe nwere ike ime ka ọ dị ka ihe na-abaghị uru.

Nke a bụ ihe atụ ole na ole nwere ike iduga n'echiche na oghere magnetik bụ efu n'ime cylinder:

1. Ọta
2. Magnetization Uniform

Ọ dị mkpa iburu n'obi na oghere ndọta dị n'ime magnetik cylindrical ga-adabere n'ihe dị iche iche, gụnyere nkesa magnetization, ọdịdị magnet, ihe onwunwe, na mmetụta mpụga dị ka oghere magnetik dị nso ma ọ bụ mkpuchi. N'izugbe, enwere ike gbakọọ ma mee ka ike magnetik dabere na ihe ndị a, mana ogige ahụ agaghị abụ kpọmkwem efu n'ime cylinder magnetized na-enweghị 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.

Ebe ndọta dị n'ime na n'èzí magnetik cylindrical na-adabere n'ụdị dị iche iche, gụnyere ụkpụrụ magnetization, njirimara ihe, na geometry nke cylinder. Ka anyị tụlee ihe atụ ole na ole:

1. Silinder Magnetized n'otu n'otu
2. Cylinder magnetized nke radially
3. Silinda oghere demagnetized
4. Silinder Ọta Igwe Ọdụdọ

Ndị a bụ nkọwa dị mfe, na omume n'ezie nke oghere magnetik nwere ike ịdị mgbagwoju anya dabere na ọnọdụ na echiche ndị akọwapụtara. Na omume, a na-enyocha nkesa magnetik site na iji ụdị mgbakọ na mwepụ ma ọ bụ sọftụwia simulation nke na-eburu n'uche njirimara zuru ezu nke magnet na gburugburu ya.
