Abstract

The results of this study aim to investigate the significant impact of electric currents on the magnetic fields surrounding a straight wire conducting current. This phenomenon is a result of the relationship between electric current and magnetic fields, making it a primary focus of scientific research in the field of physics. The method used in this research is descriptive quantitative, with a thorough analysis of the magnetic effects produced by copper wire applied to iron nails. This study found that the intensity of the magnetic field is very high when the number of copper wire turns reaches 20 turns, resulting in an increase in the attracted nails to 10 nails. This shows that the addition of the number of turns affects the magnetic strength in influencing ferromagnetic objects. This research provides a clear depiction of the relationship between electric current and magnetic fields.

Abstract

Digital financial service developments have also increased the use of digital wallet applications among university students, especially boarding house residents who have relatively high daily transaction needs. This study was conducted to examine the ease of use level of digital wallet applications by applying the System Usability Scale (SUS) approach. The research data were obtained through questionnaire distribution to 20 respondents who actively use digital wallet applications. Furthermore, the collected data were processed to determine the system usability level based on the SUS score obtained. The results showed an average SUS score of 74, which falls into the acceptable category with grade B and adjective rating Good. Although the application has been able to provide a fairly positive user experience, several aspects still require improvement, particularly in navigation arrangement and interface consistency.
