No. 13 --------- Diket : Jumlah lilitan toroida, N = 1000 lilitan Jari - jari dalam, R1 = 25 cm Jari - jari luar, R2 = 75 cm Induksi magnetik, B = 8 x 10⁻⁹ Wb/m² μo = 4π x 10⁻⁷
Tanya : Kuat arus listrik, i = __?
Jawab :
Step 1 -------- Cari dulu jari-jari efektif nya, r = __? Gunakan rumus : r = 1/2. (R1 + R2) r = 1/2. (25 + 75) r = 1/2. (100) r = 50 cm r = 0,5 m
Step 2 --------- Induksi magnetik pada Toroida B = μo.i.N / (2π.r) 8 x 10⁻⁹ = 4π x 10⁻⁷. i. 1000 / (2π. 0,5) 8 x 10⁻⁹ = 4π x 10⁻⁴. i / π 8 x 10⁻⁹ = 4 x 10⁻⁴. i i = [8 x 10⁻⁹] / [4 x 10⁻⁴] i = 2 x 10⁻⁵ Ampere

No. 13---------
Diket :
Jumlah lilitan toroida, N = 1000 lilitan
Jari - jari dalam, R1 = 25 cm
Jari - jari luar, R2 = 75 cm
Induksi magnetik, B = 8 x 10⁻⁹ Wb/m²
μo = 4π x 10⁻⁷
Tanya :
Kuat arus listrik, i = __?
Jawab :
Step 1
--------
Cari dulu jari-jari efektif nya, r = __?
Gunakan rumus :
r = 1/2. (R1 + R2)
r = 1/2. (25 + 75)
r = 1/2. (100)
r = 50 cm
r = 0,5 m
Step 2
---------
Induksi magnetik pada Toroida
B = μo.i.N / (2π.r)
8 x 10⁻⁹ = 4π x 10⁻⁷. i. 1000 / (2π. 0,5)
8 x 10⁻⁹ = 4π x 10⁻⁴. i / π
8 x 10⁻⁹ = 4 x 10⁻⁴. i
i = [8 x 10⁻⁹] / [4 x 10⁻⁴]
i = 2 x 10⁻⁵ Ampere
