Dit.
Gaya pd kawat persegi panjang.
Jawab
Fad = μ₀.i₁.i₂.lad/2πr₁
Fad = 4π.10⁻⁷.10 .5 .0,2 /(2π.1.10⁻²)
Fad = 2.10⁻⁴ N ke kiri
Fbc = μ₀.i₁.i₂.lbc/2πr₂
Fbc = 4π.10⁻⁷.10 .5 .0,2 /(2π.10.10⁻²)
Fbc = 0,2.10⁻⁴ N ke kanan
Gaya pada kawat persegi panjang
F = Fad - Fbc
F = 2.10⁻⁴ - 0,2.10⁻⁴
F = 1,8.10⁻⁴
F = 180.10⁻⁶ N
