INVESTIGATION OF THE CHANGE INDUCTANCE OF A COIL AS AIR-IRON-SILICON STEEL AND ALUMINUM CORES

Abstract

Coils are one of the basic circuit elements of electrical and electronic systems, and their difficulty against the electric current has been known as inductance. So, inductance is a measure of the coils resisting current flow and is the energy storage capacity of the coils. Inductance; It depends on factors such as the number of turns of the coil, the wire cross-section and diameter, the type of core, and the frequency. In the study, the inductance effect of the core to the coil wound on the square carcass; has been experimentally investigated for air, silicon steel, iron, and aluminum environment. In the results obtained, it has been seen that the permeability of the magnetic core material and the effect of the fukolt brake for aluminum are important. The interpretation has been made by examining the effect of inductance in changing alternating voltage values in the core environment.
