Introduction

The LEAI-21A Zeeman Effect Apparatus with Electromagnet is a cutting-edge experimental system designed to explore the Zeeman effect in atomic physics. The Zeeman effect is essential in verifying the existence of atomic magnetic moments and spatial quantization, which are critical in understanding electron spin and atomic energy levels. This apparatus uses an electromagnet to generate the Zeeman splitting of the Mercury spectral line at 546.1 nm, which produces π and σ lines. Students can also observe both transverse and longitudinal Zeeman effects using this system.

The system includes a direct reading microscope to measure the interference pattern produced by a Fabry-Perot (F-P) etalon and allows the use of an optional CCD camera with analytical software to capture and analyze the pattern. This apparatus is capable of observing the Zeeman effect in other Mercury spectral lines (such as 577 nm, 436 nm, and 404 nm) with additional filters.

The instruction manual provides a comprehensive guide to experimental setups, principles, and step-by-step instructions for conducting experiments, making it a valuable tool for learning atomic physics and magnetism in advanced physics laboratories. Please click Experiment Theory and Contents to find more information about this apparatus.

Using this instrument, the following experiments can be conducted:

1. Understand Atomic Magnetic Moment and Spatial Quantization in Atomic Physics:

   The primary goal of this experiment is for students to observe and understand the atomic magnetic moment and spatial quantization in the context of the Zeeman effect. This experiment provides insights into the magnetic properties of electrons and their interactions with external magnetic fields.

2. Observe Transverse and Longitudinal Zeeman Effects of Mercury at 546.1 nm:

   Students will observe the transverse and longitudinal Zeeman effects of Mercury at the 546.1 nm spectral line. The apparatus allows students to visualize both the transverse and longitudinal shifts in spectral lines, which is crucial for understanding how the magnetic field affects atomic energy levels in different orientations.

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

   The Zeeman effect causes the splitting and polarization of the Mercury spectral line at 546.1 nm. Students will observe this phenomenon and learn about the influence of a magnetic field on the polarization and separation of atomic spectral lines. This will deepen their understanding of magnetic interactions at the atomic level.

4. Determine the Electron Charge-Mass Ratio (e/m) Based on Zeeman Splitting Amount:

   By measuring the Zeeman splitting and relating it to the properties of the magnetic field, students can calculate the electron charge-to-mass ratio (e/m). This experiment connects the Zeeman effect with key concepts in electron dynamics and provides a practical application for determining fundamental physical constants.
