An inductor has 1,000 turns of wire and a cross sectional area of 0.001m2. If the core has a permeability of 0.000,001 and the coil is 0.1m. What is the value of the inductor?
- 100microH.
- 100mH.
- 10mH.
Explanation from PART66Online
Inductance of a coil is L = micro*N^2*A / l. Substituting: (0.000001 * 1000^2 * 0.001) / 0.1 = (1e-6 * 1e6 * 0.001) / 0.1 = 0.001 / 0.1 = 0.01H = 10mH. The result scales with the square of turns and the core permeability, and inversely with the magnetic path length.
