Principle

The magnetic permeability of an iron core ensures that the magnetic flux density of a current carrying coil increases significantly. This difference can be quantitatively determined with the aid of a magnetic field sensor.

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

  1. measure the magnetic flux density of two coils at direct current with and without iron core as a function of the current intensity. Calculate the magnetic permeability of the iron core.
  2. measure the magnetic flux density of two coils in alternating current with and without iron core. Calculate the magnetic permeability and compare the result with the first task.

Learning Objectives

The magnetic permeability is measured quantitatively. The resulting results for direct current and alternating current will be compared.
