Electromagnetic induction with Cobra SMARTsense

Principle

In this experiment, the process of electromagnetic induction and its benefits are to be investigated.

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

The students are to drive a permanent magnet mounted at right angles to the axis of rotation with the help of a crank and a belt and thus set it in rotation.

Then they are to bring a coil with an iron core close to the rotating permanent magnet and measure the voltage or current generated.

Learning Objectives

In this experiment the process of electromagnetic induction and its benefits shall be worked out and understood.
