Unknown Principle Coils are built into many electronic objects. They are installed, for example, in transformers, electric motors or loudspeakers. Coils only generate a magnetic field when they are connected to a power source. Benefits - 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.
Tasks - measuring the magnetic flux density within the 26mm Ø coil with a winding of 75 with increasing current intensity.
- measuring the magnetic flux density inside the 26mm Ø coil with a turn of 300 with increasing current.
Learning Objectives In this experiment the magnetic flux density as a function of the current intensity is to be investigated. Two coils with different winding density are used and compared. Scope of delivery |
