Uphando olutsha luyayandisa indima ye Umhlaba umhlaba wemagnethi. Ukongeza ekukhuseleni umhlaba ukusuka kumasuntswana ahlawulisiweyo ayingozi kwimoya yelanga engenayo, ikwalawula indlela amandla eveliswayo (ngamasuntswana ahlawuliweyo kwimimoya yelanga) isasazwa phakathi kweepali ezimbini. Kukho ukhetho olusemantla okuthetha ukuba amandla amaninzi ajikelwa kwipali esemantla enemagnethi kunepali yemagnethi yasemazantsi.
umhlabaumhlaba wemagnethi, uyilwe ngenxa yokuqukuqela kolwelo olushushu kakhulu kumbindi ongaphandle we umhlaba ngaphantsi kwe-3000 km ukusuka phezulu kudlala indima ebalulekileyo ebomini bethu. Iphambukisa umsinga wamasuntswana ahlawuliweyo aphuma eLangeni kude umhlaba ngaloo ndlela ikhusela ubomi kwimiphumo eyingozi ye-ionizing imimoya yelanga.
Xa amasuntswana atsalwa ngumbane kumoya welanga ehamba emoyeni, avelisa amandla. La mandla ombane wombane asemhlabeni aqondwa ukuza kuthi ga ngoku njengokuba asasazwa ngokulinganayo phakathi kweepali ezisemantla nezisezantsi. Nangona kunjalo, uphando olutsha lusebenzisa idatha evela kwisathelayithi ye-Swarm kwi-polar low-umhlaba ukuhamba (LEO) kumphakamo ojikeleze i-450 km, ibonise ukuba oku akunjalo. Amandla akhethwa ngokukhethekileyo kwi-pole North. Le asymmetry yokhetho lwasemantla ithetha ngaphezulu kweentloko zamandla ombane osemhlabeni ukuya kwipali esemantla enemagnethi kunesingise kwipali yemagnethi emazantsi.
Imagnethi yomhlaba Ngoko ke, ikwadlala indima ekusasazeni nasekuhambiseni umjelo wamandla ombane osemhlabeni (aveliswe ngenxa yokungena kwamasuntswana atshajelwe ngombane) emoyeni.
Ionizing radiations kwi yelanga Umoya uyaziwa ngokuba namandla okudala umonakalo kuthungelwano lonxibelelwano, iinkqubo zokukhangela ezisekwe kwisathelayithi kunye neegridi zombane. Ukuqonda ngcono Emhlabeni imagnethi iya kuba luncedo ekucwangciseni ukhuseleko kunye nokukhuselwa kwimimoya yelanga.
