Magnet ni ikintu gisanzwe kandi cyingenzi, gikoreshwa cyane mubuzima bwa buri munsi no mu nganda. Mubuzima bwa buri munsi, magnesi zikoreshwa mugukosora ibintu, nkikidodo cyumuryango wa magneti hamwe nigikombe cyokunywa kumiryango ya firigo, gishobora kwemeza gushya numutekano wibiribwa. Byongeye kandi, magnesi zikoreshwa kandi nk'imitako ku mitako yo mu nzu hamwe n'abafite amafoto ku rukuta rw'amafoto, bizana ubwiza no korohereza ubuzima. Mu musaruro winganda, magnesi zikoreshwa cyane. Magneteti akoreshwa cyane muri moteri na generator, akoresha imbaraga za magneti kugirango agere ku mbaraga no guhinduranya imashini. Byongeye kandi, magnesi zikoreshwa kandi mu byuma bifata ibyuma bikoresha ibikoresho kugira ngo zibone amakuru kandi zikurikirane impinduka z’ibidukikije zumva impinduka mu murima wa rukuruzi. Kurugero, compas ni sensor ikoresha magnesi kugirango ifashe abantu kwiyobora.
