Analysis of the impedance variation versus the inclination of a coil with ferrofluid core

Corneliu Buzduga, Abdelkader Benabou


This article focuses on the study of a coil the air gap with ferrofluid. The coil used is basically a glass tube that was wound 22 turns and 100 turns of copper wire of 1 mm thickness. By tilting the coil with a resolution of 10 degrees, in descending order I noticed that the amount of coil impedance changes.


air gap, coil, ferrofluid, inductance, impedance.
