Force between parallel wires

F/L = μ₀I₁I₂/(2πd)

Where: F = force (N), I₁ = I₁, I₂ = I₂, L = length (m) / angular momentum / inductance, d = distance / slit separation (m), μ₀ = permeability of free space (T·m/A)

Solved example

Given: I_1 = 7, I_2 = 5, L = 10, d = 4, mu_0 = 3
Find: F (force (N))

  1. Formula: F/L = I₁·I₂·μ₀/(2·π·d)
  2. Rearranged for F: F = I₁·I₂·L·μ₀/(2·π·d)
  3. Substitute the values: F = 10·3·5·7/(2·π·4)
  4. Result: F = 41.778173

Answer: F = 41.778173 N/m
