Magnetic flux density of a coil in dependence of the current with Cobra SMARTsense

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

1. measuring the magnetic flux density within the 26mm Ø coil with a winding of 75 with increasing current intensity.
2. 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.
