With these high-quality materials, students from grade 9 onwards can carry out important experiments on the topic of induction and alternating voltage themselves. Motivated by captivating examples from everyday life, they safely work out with this class set how magnetism and electricity interact. For example, what happens in a coil when electricity flows through it? How do the magnetic fields around a current-carrying conductor and a coil differ?
- All student experiments are developed according to safety regulations: current limit < 3 A, voltage up to 12 V, output voltage at the transformer up to 4 V AC
- The U-I core is available six times in the class set for parallel work by the learning groups.
- The completeness of the experiment materials can be checked at a glance.
Tip: For the self-induction experiment, you also need some parts that are not included in the 54075 class set (see accessories). Alternatively, you can find all these small parts in the supplementary set 54076.

In the accompanying material
- The teacher's manual is didactically prepared and suitable for immediate use.
- All student worksheets are available as editable Word versions for free download.
- The experiments are enriched with a list of materials, instructions for carrying them out, evaluation and tips for you as a teacher. QR codes for internal differentiation, hint boxes, formula support and many 3D illustrations offer individual help to the learners.
Topics that are additionally covered
- Magnetic fields of current-carrying conductors and coils
- Induction in coils
- Lenz's rule
- Delayed switch-on process with parallel connection of L and R, switch-on and switch-off processes with coils
The influence of the coil parameters winding number, current and permeability on the strength of the magnetic field is qualitatively investigated. The strength of the magnetic field is assessed according to how strongly an iron sheet strip is attracted to the upper end of an I-core located in the coil.
