Transformers are based on the principle of electromagnetic induction. Transformers are a widely used component in electrical engineering. The main task of a transformer is to convert an input voltage into another output voltage. Other examples of applications are electric toothbrushes or smartphones that can be charged wirelessly.


  • Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions.
  • Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
  • Increased motivation of students by using the intuitive measureAPP.
  • Increased media competence.


  1. measuring the induced voltage without iron core in the coils.
  2. measuring the induced voltage with iron core in the coils.

Learning Objectives

This experiment is intended to bring the principle of electromagnetic induction closer. A current is induced in a coil by an alternating magnetic flux. The effect of an iron core in the two coils is studied.
