Earth's magnetic field strength and direction with Cobra SMARTsense

Principle

The magnetic field is sufficient. There's a north and south pole. The field from the north to the south pole is defined as positive and from the south to the north pole as negative. As an example of use, a compass can be mentioned here, which serves our navigation. The magnetic north pole is not the same as the geographic north pole. The magnetic poles of the earth move and are not completely static.

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

Measure the Earth's magnetic field.

Learning Objectives

In this experiment the magnetic field direction and the magnetic field strength of the earth shall be investigated.
