Fito daga arewa iyakacin duniya na maganadisu da kuma mika su zuwa kudu. A ciki na maganadisu duk tsananin m. A Lines ba su da wata farkon ko karshen, ana rufe ko ne daga rashin iyaka zuwa rashin iyaka.

Waje da maganadisu Lines ne mafi densely kusa da sandunan. Daga wannan ya bayyana cewa mafi karfi da tasiri a filin kusa da sandunan, da kuma nĩsa daga kasa shi raunana. Ganin cewa Magnetic tube an lankwasa, shugabanci na karfi aiki a kan wani Magnetic allura, kuma an canja.

Yadda za a zana

Don gane da bambance-bambance tsakanin mai uniform Magnetic filin na iri-irin, shi yana bukatar ya koya su nuna yin amfani da Magnetic Lines.

Misali abin da ya faru uniform Magnetic filin kamata a yi la'akari a cikin sama mai suna ake kira solenoid wanda yake shi ne cylindrical waya nada ta hanyar abin da na yanzu da aka yarda. Ciki da shi, a Magnetic filin za a iya daukan kama, bayar da cewa tsawon shĩ ne mafi girma fiye da diamita (waje filin coils zai zama ba uniform, Magnetic Lines za a sanya kazalika da band-izinin magnet).

Uniform filin da aka ma located in tsakiyar m maganadisu tsiri. A wata iyaka yankin a sarari yake zai yiwu a haifa da kuma uniform Magnetic filin, a cikin abin da tasiri da karfi a kan wani magnetized kibiya za ta zama daidai a cikin girma da kuma shugabanci.

Don su dace da halin maganaɗisu filin, ta amfani da wadannan misali.
