Introduction

The LEAI-20 Zeeman Effect Apparatus with Permanent Magnet is designed to provide students with a hands-on experience in observing and understanding the Zeeman effect. This apparatus consists of several key components, including a main unit with a Teslameter and light source power supply, a permanent magnet, a pencil Mercury lamp, focusing/imaging lenses, an interference optical filter, a Fabry-Perot (F-P) etalon, a polarizer, a direct reading microscope, and optional devices such as a CCD camera, USB image acquisition box, and analysis software.

The system is intended for advanced physics laboratories and is equipped with all the tools needed to observe the Zeeman effect, a crucial phenomenon in atomic physics. The instruction manual includes detailed materials on experimental configurations, theoretical principles, and step-by-step instructions to guide students through each experiment. Please click Experiment Theory and Contents to find more information about this apparatus.

Using this instrument, the following experiments can be conducted:

1. Observe the Zeeman Effect and Understand Atomic Magnetic Moment and Spatial Quantization:

   The apparatus allows students to observe the Zeeman effect, the splitting of spectral lines under the influence of a magnetic field. This experiment provides a deeper understanding of atomic magnetic moments and spatial quantization in atomic physics. By observing the effect, students can relate it to the quantization of angular momentum and energy levels.

2. Observe the Splitting and Polarization of a Mercury Atomic Spectral Line at 546.1 nm:

   Using the Mercury lamp, students can observe the splitting and polarization of the spectral line at 546.1 nm as it undergoes the Zeeman effect. This experiment demonstrates how magnetic fields can alter atomic spectral lines and provides insight into the polarization of emitted light.

3. Calculate the Bohr Magneton Based on Zeeman Splitting Amount:

   The apparatus allows students to calculate the Bohr magneton from the observed Zeeman splitting. The Zeeman effect is directly related to the magnetic moment of electrons, and this experiment allows students to measure and calculate this fundamental physical constant.

4. Learn How to Adjust a Fabry-Perot Etalon and Apply a CCD Device in Spectroscopy:

   The system includes a Fabry-Perot (F-P) etalon, a tool used to observe the fine structure of spectral lines. Students will learn how to adjust the etalon and apply a CCD device (optional) in spectroscopy to obtain high-resolution images of spectral lines. This part of the experiment enhances students' knowledge of optical techniques and modern spectroscopy.
