1. Ngokusekelwe esithombeni esingezansi, uma irediyasi yokugoba kwentambo ingu-50 cm, nquma ubukhulu bensimu yamagnetic enkabeni yokugoba (ephuzwini 0, bheka isithombe esingezansi). (µ o = 4π.10 -7 Wb.A -1 m -1 )
Kwaziwa:
Irediyasi (r) = 50 cm = 0.5 m
Amandla kagesi (I) = 1.5 Ampere
Ukuvuleka kwe-vacuum (µo ) = 4π.10 -7 Wb.A -1 m -1
Okufunwayo: Ubukhulu bensimu yamagnetic
Isixazululo:
360 o = 1 isiyingi sendilinga . 120 o / 360 o = 1/3 bese kuthi 120 o = 1/3 x isiyingi sendilinga.
Isibalo sensimu yamagnetic enkabeni yekhoyili enama-loops amaningana:
B = ubukhulu bensimu yamagnetic, N = inani lezihibe, I = ugesi wamanje, r = irediyasi yokugoba
Enkingeni engenhla, kukhona iluphu eyodwa kuphela ukuze u-N akhishwe kulesi sibalo. Ikhoyili yentambo enkingeni engenhla akuyona indilinga eyodwa kodwa iyindilinga engu-1/3:
Ubukhulu bensimu yamagnetic enkabeni yokugoba:
2. Ngokusekelwe esithombeni esingezansi, ukugeleza kwamandla kagesi entanjeni kungu-6-A kanti irediyasi yokugoba ingu-R = 3π cm, ukuthola ubukhulu bensimu yamagnetic endaweni engu-P.
Kwaziwa:
Irediyasi yokugoba (r) = 3π cm = (3π/100) m
= 3π/10 2 m = 3π.10 -2 m
Amandla kagesi (I) = 6 A
Ukuvuleka kwe-vacuum (µo ) = 4π.10 -7 Wb.A -1 m -1
Okufunwayo: Ubukhulu bensimu yamagnetic
Isixazululo:
360o = 1 umjikelezo yesiyingi. 45o / 360o = 1/8 bese kuba ngu-45o = 1 / 8 x umjikelezo yesiyingi.
Ubukhulu bensimu yamagnetic enkabeni yokugoba:
3. Ukugeleza kwamandla kagesi ku-wire = 9-A, irediyasi yokugoba (R) = 2π cm kanye no-µ o = 4π.10 -7 Wb.A -1 .m -1 , kunquma ubukhulu bensimu yamagnetic endaweni P.
Kwaziwa:
Irediyasi yokugoba (r) = 2π cm = (2π/100) m
= 2π/10 2 m = 2π.10 -2 m
Amandla kagesi (I) = 9 A
Ukuvuleka kwe-vacuum (µo ) = 4π.10 -7 Wb.A -1 m -1
Okufunwayo: Ubukhulu bensimu yamagnetic endaweni P
Isixazululo:
360o - 120o = 240o. 240o / 360o = 2/3 bese kuba ngu-240o = 2/3 x umjikelezo yesiyingi.
Ubukhulu bensimu yamagnetic enkabeni yokugoba:
