An angular scale is used to investigate the deflection of beta rays in the magnetic field.
- 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.
The students investigate the deflection of beta rays in the magnetic field by moving the Geiger-Müller counter tube on the angular scale of the mounting plate and detecting the pulse rate.
In this experiment, various findings can be conveyed:
- β rays consist of electrically charged particles because they are deflected by a magnet.
- Since the direction of the deflection is opposite to the direction expected according to the three-finger rule, β particles have a negative charge.
- The stronger the magnetic field, the greater the deflection. When the field direction is changed, the deflection is also in the opposite direction.
- The β particles have different energy values because they are deflected to different degrees.
