The inductance of a solenoid 16.0 cm long with a cross-sectional area of 1.00 × 10^-4 m² is 1.00 mH. How many turns of wire does this solenoid have?

Question

Quizplus · Accepted Answer

The inductance L of a solenoid is given by L = (μ₀ * N² * A) / l, where μ₀ is the permeability of free space (4π × 10⁻⁷ T·m/A), N is the number of turns, A is the cross-sectional area, and l is the length. Solving for N gives approximately 1130 turns.
