میدان مغناطیسی اطراف آهنربای مکعبی

 

آهنربا ها (Magnets) در اشکال و اندازه های گوناگون و برای مصارف مختلفی ساخته می شوند . به علت اشکال مختلفی که آهنربا ها دارند برای ساخت آن ها از قالب ریزی استفاده می شود .

ابتدا قالب های مورد نظر برای شکل مورد سفارش ساخته می شوند . سپس با استفاده از مواد فلزی گوناگون یک نوع آلیاژ فرومغناطیس مذاب را تهیه می کنند . این آلیاژ را درون قالب های طراحی شده می ریزند تا شکل بگیرد .

پس از جدا کردن آهنربا های شکل گرفته در مراحل بعدی با استفاده از قرار دادن آن ها در میدان باعث یکسو شدن دوقطبی های مفناطیسی درون آن ها ، خاصیت آهنربایی پیدا می کنند .

هر چه خاصیت فرومغناطیسی آلیاژ مورد استفاده بیشتر باشد و میدانی که به آهنربا اعمال می شود قوی تر باشد ؛ آهنربای قوی تری خواهیم داشت .

برای افزودن قدرت یک آهنربا می توان آن را در یک میدان همسو با دوقطبی های مغناطیسی قرار داد تا تعداد دو قطبی های مغناطیسی هم سو شده افزایش یابند .

در ادامه شما برای آشنایی کامل با ساخت آهنربا ها یک فیلم ویدیویی و یک مقاله تهیه کرده ایم ....امید وارم لذت ببرید

    Today, I went to the beach with my children. I found a
    sea shell and gave it to my 4 year old daughter and said
    "You can hear the ocean if you put this to your ear." She
    put the shell to her ear and screamed. There was a hermit crab inside and
    it pinched her ear. She never wants to go back!
    LoL I know this is totally off topic but I had to tell someone!
