Solenoid Inductance
Formula
L = μ₀ × n² × A × l = μ₀ × N² × A / l, where μ₀ = 4π × 10⁻⁷ H/m, N is number of turns, A is cross-section area, and l is solenoid length.
Frequently Asked Questions
What is inductance?
Inductance is the tendency of an electrical conductor to oppose a change in the current flowing through it. It is measured in henries (H).
How does solenoid geometry affect inductance?
Inductance increases with more turns, larger cross-section area, and shorter coil length. Specifically, L = μ₀N²A/l, so it scales with the square of the number of turns.
