Kofin Magnet Amfani da Hankali
Dakarun jan hankali na Kofin Magnet na iya haifar da mummunan rauni. A yadda aka saba muna sanya sandar S ta zama fuskar dukkan kofin magnet, don haka kofin magnet ba zai iya jawo hankalin juna da fuska ba, amma babban kofin magnet mai girma, kamar ME60, da sauransu.
Wadannan kofuna na maganadisu an yi su ne da maɗaukakin neodymium, kuma magnetin neodymium suna da ƙarfi fiye da kowane nau'in maganadiso, don haka ƙarfin jan hankali na iya zama da ƙarfi fiye da tunanin ku har ma suna jan ƙarfe na yau da kullun.
Kuma ana iya tsunkule yatsu da sauran sassan jiki tsakanin kofuna na maganadisu biyu, za a iya samun rauni mai tsanani idan ba a yi taka tsantsan ba.
Ba za a iya amfani da waɗannan kofuna na maganadisu a cikin kayan wasan yara ba, musamman don manyan kofuna na maganadisu, ba su dace da amfani da su a wurin wasan yara ba, bai kamata a ƙyale yara su rike kofuna na magnetin neodymium ba.
