Centre of circular loop

B = μ₀I/(2R)

Where: B = magnetic field (T), I = moment of inertia (kg·m²) / current (A), R = range / radius / resistance, μ₀ = permeability of free space (T·m/A)

Solved example

Given: I = 7, R = 5, mu_0 = 10
Find: B (magnetic field (T))

  1. Formula: B = I·μ₀/(2·R)
  2. Substitute the values: B = 10·7/(2·5)
  3. Result: B = 7 T

Answer: B = 7 T
