Introduction

Hall devices are widely used for magnetic field measurements due to their small size, ease of use, high accuracy, and ability to measure both AC and DC magnetic fields. In addition, when combined with other devices, Hall sensors can be utilized for automatic control and the measurement of position, displacement, speed, angle, and various other physical quantities.  

The LEEI-35 Hall Effect Experimental Apparatus is designed to help students:  

- Understand the principle of the Hall effect.  

- Measure the sensitivity of a Hall element.  

- Learn how to use a Hall element to measure magnetic field intensity.  

This apparatus offers several key features:  

1. High-performance GaAs Hall element: Provides high sensitivity, a wide linear range, and a low temperature coefficient.  

2. Low working current: Ensures stable and reliable experimental data.  

3. Visible structure: The shape and structure of the test sample and Hall element make results intuitive and easy to understand.  

4. Durable design: Includes a protective mechanism for long-lasting use.  

The following experiments can be conducted using this apparatus:  

1. Determine the relationship between Hall current and Hall voltage under a DC magnetic field.  

2. Measure the sensitivity of a GaAs Hall element.  

3. Obtain the magnetization curve of silicon steel using a GaAs Hall element.  

4. Measure the magnetic field distribution along the horizontal direction using a Hall element.  

The instruction manual includes detailed experimental configurations, theoretical principles, step-by-step instructions, and examples of experimental results. For additional details, please click Experiment Theory and Contents  to learn more about this apparatus.
