Inductance vs Number of Turns
Formula
## Solenoid Inductance Inductance quantifies the ability of a coil to store energy in a magnetic field. ### Formula **L = mu_0 * N² * A / l** where N is the number of turns, A is the cross-sectional area, and l is the solenoid length.
Exemplo Resolvido
A solenoid with 100 turns, area 0.001 m², length 0.1 m.
- 01L = mu_0 * N² * A / l
- 02L = 4*pi*1e-7 * 10000 * 0.001 / 0.1
- 03L = 1.2566e-3 * 0.01
- 04L = 1.2566e-5 H = 0.1257 mH
Perguntas Frequentes
What is inductance?
Inductance is the property of a conductor that opposes changes in current. A changing current through an inductor induces a voltage that resists the change.
How does a ferrite core affect inductance?
A ferrite core increases the effective permeability (mu = mu_r * mu_0), multiplying the inductance by the relative permeability mu_r of the core material.
What is the unit of inductance?
The henry (H), named after Joseph Henry. One henry means a current change of 1 A/s induces 1 volt.
