Toroid (Magnetism & electromagnetic induction)
B = μ₀NI/(2πr)
Where: B = magnetic field (T), I = moment of inertia (kg·m²) / current (A), N = number of turns / normal force (N), μ₀ = permeability of free space (T·m/A), r = radius / distance (m)
Solved example
Given: I = 7, N = 5, mu_0 = 10, r = 4
Find: B (magnetic field (T))
- Formula: B = I·N·μ₀/(2·π·r)
- Substitute the values: B = 10·5·7/(2·π·4)
- Result: B = 13.926058
Answer: B = 13.926058
