Building a Science Kit of Faraday’s Law with Free Fall Motion Method

Abstract

The aim of this study is to build a science kit of Faraday’s Law with free fall motion method. The magnetic flux comes from several neodymium magnets and the coil is made of copper. The moving magnet falling through the coil causes a change in the magnetic flux and produces an induced emf. The data analysis technique used in this research are graphical method and analysis of Faraday’s Law equations with another supporting equation. Based on the results of this study, the conclusion is the induced emf value is directly proportional with the change of the magnetic flux and also has a directly proportional with the number of turn of coil, thus it can be obtained the mathematical equation of Faraday’s Law ε = d ϕ B d t
