# Augmenting the fine beam tube: From hybrid measurements to magnetic field visualization

## TL;DR

This paper introduces an AR-enhanced, networked fine beam tube experiment that allows students to digitally record measurements, visualize magnetic fields, and better understand the relationship between experimental data and theoretical concepts.

## Contribution

It presents a novel AR-based platform for physics education that integrates measurement, visualization, and theoretical overlay to improve learning outcomes.

## Key findings

- More accurate determination of e/m ratio
- Enhanced student understanding through visualization
- Integration of digital measurement and AR overlays

## Abstract

We present an Augmented Reality (AR) enhanced and networked fine beam tube experiment for undergraduate physics education. In order to determine the charge-to-mass ratio of the electron students are able to record all measurement values digitally within the AR-environment wearing a head-mounted AR device. Besides more accurate determination of $\frac{e}{m_e}$ it offers the possibility to overlay additional data such as a magnetic field visualization or formulas in order to foster the students' understanding of relations between experiment and theory.
