Expression for self inductance of a solenoid
WebSep 12, 2024 · From a practical point of view, the infinite solenoid is one whose length is much larger than its radius ( L >> R). In this case, θ 1 = − π 2 and θ 2 = π 2. Then from Equation 12.7.6, the magnetic field along the central axis of an infinite solenoid is … WebThe number of turns per unit length can be calculated by dividing the total number of turns by the length of the solenoid: n = N L. where N is the total number of turns and L is the length of the solenoid. Substituting the given values, we have: n = N L = 2,000 0.25 = 8,000 turns/meter. I = 5 A. μ ₀ π μ ₀ = 4 π × 10 − 7 T m A.
