Dabi na Uku da Karamin Iccen Fleming Tushen Daaka

Misalai da Koyarren Faring na Haukari da Biyu?

Idan conductor na da current yake cika magnetic field, zai iya kasance wasu karamin lura a kan conductor. Yadda ake samun hawan wannan karamin lura zai iya tabbatar da Koyarren Faring na Haukari (ko kuma ‘Koyarren Faring na haukari da aka fi sani don motors’).

Duk da haka idan conductor an yi gaba-gaban zuwa magnetic field, zai iya kasance wasu current a cikin wannan conductor. Yadda ake samun hawan wannan karamin lura zai iya tabbatar da Koyarren Faring na Haukarri.

A cikin Koyarren Faring na haukari da biyu, akwai nau'in da ke nuna alama daga magnetic field, current, da karamin lura. Wannan nau'in ta ce Koyarren Faring na haukari da Koyarren Faring na haukarri sun tabbatar da shi ne.

Wannan koyarren ba su tabbatar da tsarin karamin lura ba, amma suke nuna hawan abubuwan uku (magnetic field, current, karamin lura) idan hawan labaran biyu suna sanin.

Koyarren Faring na Haukari ya zama mai karatuwa a electric motors kuma Koyarren Faring na Haukarri ya zama mai karatuwa a electric generators.

An samu cewa idan conductor na da current an kara shi a cikin magnetic field, zai iya kasance wasu karamin lura a kan conductor, a hawan da ba a hawan current ko magnetic field.

A cikin wannan hoton, wata baki na conductor tana da girman ‘L’ an kara shi a cikin magnetic field na da tsarin ‘H’, wanda an yi shi a kan magnetic poles N da S. Idan current ‘I’ yake gudana a cikin wannan conductor, tsarin karamin lura wanda yake kasance a kan conductor ita ce:

Kara haukar da kaɗi, hankali, da kuma hankali na biyu a hawan da suka fi inganta. Idan hankali na kaɗi ya nuna hawan magnetic field da hankali na biyu ya nuna hawan current, hankali na uku ya nuna hawan karamin lura.

Idan current yake gudana a cikin conductor, zai iya kasance wasu magnetic field a kan ita. An iya sauki wannan magnetic field da waɗanda suka haifar da closed magnetic lines of force a kan conductor.

Yadda ake samun hawan magnetic lines of force zai iya tabbatar da Maxwell’s corkscrew rule ko kuma right-hand grip rule.

Idan an tabbatar da wannan rules, yadda ake samun hawan magnetic lines of force (ko kuma flux lines) ya zama clockwise idan current yake gudana daga wajen magance, ciki har da hakan hakan da yadda ake samun current a cikin conductor yana ƙare daga reference plane kamar yadda aka bayyana a hoton.

Idan an kara horizontal magnetic field a kan conductor, wannan magnetic fields biyu, wanda adi na magnetic field a kan conductor saboda current a cikin ita da magnetic field na da aka kara shi, zai iya ɗaukan da suka haifar da su.

An samu cewa magnetic lines of force na external magnetic field suna nufin N zuwa S pole, wato daga hagu zuwa yamma.

Magnetic lines of force na external magnetic field da magnetic lines of force na current a cikin conductor suna nufin sama a fagen conductor, kuma suna nufin ƙarshe a fen conductor.

Saboda haka za a iya samun masu yawan magnetic lines of force a fagen conductor kadan yawan da ake samu a fen conductor.

Basa ga haka za a iya samun masu yawan magnetic lines of force a wurin mafi yawa a fagen conductor. Saboda magnetic lines of force ba suka ɗauke da ɗaya, suke cikin tension wanda ake kira stretched rubber bands.

Basa ga haka za a iya samun karamin lura wanda zai iya kawo conductor daga yawan magnetic lines of force mafi yawa zuwa yawan da ake samu, wato daga hakan zuwa fagen.

Idan kana magana game da hawan current, karamin lura, da magnetic field a cikin bayanan da aka bayyana, za ku samu cewa hawan su suka fi dace da Koyarren Faring na Haukari.
