Um estudo sobre a injeção de fios magnéticos em cavidades

Abstract

In this work we created some experiments concerning about injection process of magnetic wire into a rigid circular cavity in order to get a better understanding about characteristics of the morphologies generate under certain initial conditions. Our results implies the possibility of formation of two morphologies that have different characteristics. When the two wires injected diametrically opposite, but have magnetic dipoles in opposite direction we achieve spiral morphology. In the case of the two wires injected diametrically opposite, but have magnetic dipoles in same direction we achieve loop morphology. So we make a series of statistical analysis based on the image structures, form during the injection of the wire in the cavity. As a result these analyzes we found that the loop morphology showed a size ties distribution like power law in function of the packing fraction φ, behaving as Nl / φα. The exponent α rules the behavior of a power law is quite different from those found in other works about packing wires. We believe the difference comes from to the presence of long-range forces present in magnetic systems.
