Principle

The superposition of electric fields is usually known. Magnetic fields also overlap. In this experiment this superposition is investigated. The Helmholtz coil is an example where two magnetic fields of two coils overlap.

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. measuring the magnetic flux density of two coils. The coils have the same polarity so that the magnetic fields complement each other positively.
  2. measuring the magnetic flux density along two coils. The polarity of one coil is reversed so that the magnetic fields between the coils are superimposed negatively.

Learning Objectives

In this experiment the magnetic flux density of two coils is to be measured. The superposition of two fields is investigated. In the first part the two magnetic fields are in the same direction and in the second part they are in opposite directions.
