Özet

It is well known that the needle of a compass in a magnetic field deflects, and that a compass near a conductive wire carrying a stable electric current deflects its needle. The only explanation of this observation is that the current-carrying wire creates a magnetic field around it. The strength of the magnetic field at any point near the wire depends on the strength of the current and the distance from the wire. Analysis of the magnetic field created by a long straight current-carrying wire has an important place in magnetism teaching. Therefore, the aim of this study was to develop a low-cost experimental setup to collect real-time data for the analysis of the magnetic field near a long straight wire.
