Sayensị na-ewu ewu: Ọ bụ aluminom magnetik?

Aluminom abụghị magnetik

Aluminom, akara kemikal Al, nọmba atọm 13, bụ ọla ọcha na-acha ọcha. Ọ bụ ọla kachasị ukwuu n'ime ụwa. N'ihe gbasara magnetism, Aluminom bụ nkewa dị ka ihe na-abụghị magnetik ma ọ bụ paramagnetic. Nke a pụtara na ọ naghị egosipụta magnetism siri ike dị ka ihe ferromagnetic.

Ihe ndabere nke Magnetism

Mgbe anyị na-ekwu maka magnetism, anyị na-echekarị ihe dị ka ígwè, cobalt, na nickel n'ihi mmasi ha siri ike na magnet. N'ezie, e nwere isi atọ ụdị omume magnetik nke ihe:

  1. Ferromagnetic: Ihe ndị dị ka ígwè, cobalt na nickel nwere mmasị siri ike na ndọta ma nwee ike ịghọ ihe ndọta n'onwe ha.
  2. Paramagnetic: Ihe ndị a nwere ihe na-adịghị ike na-adọrọ adọrọ na oghere magnetik na anaghị ejide magnetism ha ozugbo ewepụrụ oghere magnetik..
  3. Diamagnetism: Ihe ndị dị ka ọla kọpa na bismuth na-emepụta oghere magnetik na-abụghị nke dị n'ihu oghere magnetik ọzọ, ma ike adịghị ike nke ukwuu.

Magnetism nke aluminum

N'ihe gbasara magnetism, Aluminom bụ nkewa dị ka ihe na-abụghị magnetik ma ọ bụ paramagnetic. Nke a pụtara na ọ naghị egosipụta magnetism siri ike dị ka ihe ferromagnetic.

Paramagnetism nke aluminom na-esite na nhazi nke electrons ya. Aluminom nwere eletrọn a na-ejikọtaghị ọnụ na mpụta ya, na dị ka quantum physics si dị, Eletrọn na-ejikọtaghị ọnụ na-enye aka na paramagnetism. Agbanyeghị, n'ihi na mmetụta a adịghị ike, magnetism nke aluminom na-esikarị ike ịchọpụta na ndụ kwa ụbọchị.

Ọ bụ aluminom magnetik

Ngwa na mkpa

Ịghọta ihe ndị na-abụghị magnetik nke aluminom dị oké mkpa maka ngwa dị iche iche:

  • Onye nduzi eletrik: Mmekọrịta adịghị ike nke aluminom na oghere magnetik na-eme ka ọ bụrụ ihe dị mma maka eriri nnyefe ọkụ n'ihi na ọ naghị egbochi ọkụ eletrik..
  • Ngwa nri: Aluminom cookware na-ewu ewu n'ihi na ọ naghị eji magnetik ma ọ bụ ihe ndọta meghachi omume, nke dị mkpa maka induction cooktops.
  • Ụlọ ọrụ Aerospace: Ngwongwo na-abụghị nke aluminom na-erite uru maka ụlọ ọrụ ikuku, ebe a na-ahọrọ ihe ndị na-adịghị egbochi usoro ụgbọ elu ụgbọ elu.
  • Ngwa ahụike: Aluminom is commonly used in medical devices that require compatibility with magnetic resonance imaging (MRI) igwe.

Nwalee magnetism nke aluminom n'ụlọ

Chọrọ ịnwale magnetism nke aluminom n'onwe gị? Nke a bụ nnwale dị mfe ị nwere ike ịnwale n'ụlọ:

  1. Chịkọta ihe: Ị ga-achọ magnet neodymium siri ike na mpempe aluminom, dị ka aluminom nwere ike.
  2. Usoro: Jide ndọta nso na aluminom. Ị ga-achọpụta na aluminom anaghị arapara na magnet.
  3. Twist: Bugharịa magnet ngwa ngwa n'ebe aluminom, wee wepụ ya. Ị nwere ike ịhụ ntakịrị ịkwanye ma ọ bụ dọpụta na aluminom. Ihe na-akpata mmeghachi omume a bụ mmiri na-akpata nke a na-akpọ eddy currents, nke na-emepụta oghere magnetik na-adịru nwa oge gburugburu aluminom.
