Engine-generator with Cobra SMARTsense

Principle

The operation of the generator is based on the principle of electromagnetic induction. This means that a permanent magnet moving past an electromagnet causes a change in the magnetic flux and thus creates an electric current. With the generator, the principle is produced by the continuous rotary motion.

Benefits

• Simple design of all components so that students can easily see their function
• The functional models can be built up successively, thus the functional relationships between the individual components are well understood.
• No tools necessary
• Especially understandable and didactically prepared description of the experiment (reference 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.

Tasks

In this experiment, the students are to drive a generator with the help of an electric motor and thus generate and measure a current again.

Learning Objectives

This experiment should enable the students to recapitulate their knowledge of electric motors and electric generators that they have learned so far.
