Introduction

The magnetic hysteresis loop and magnetization curve illustrate the fundamental magnetic properties of materials. Ferromagnetic materials with diverse characteristics have been widely used in industries such as transportation, communications, electricity, and electronics.  

This experimental apparatus includes the following key features:  

1. A high-precision digital Tesla meter ensures accurate measurements.  

2. A demagnetization process is integrated for measuring DC magnetic properties. 

3. Measurement capability for magnetic field intensity distribution in a gap.  

4. Two different magnetic material specimens are included for experimentation.  

Using this apparatus, students can perform the following experiments:  

1. Determine the relationship between magnetic induction intensity (B) and position (X) in a specimen using a digital Tesla meter.  

2. Measure the range of uniform magnetic field intensity along the X-axis.  

3. Understand the process of demagnetizing a magnetic specimen and measure its initial magnetization curve and magnetic hysteresis loop.  

4. Apply Ampere's circuit law in magnetic measurements.  

The instruction manual provides comprehensive details, including experimental configurations, theoretical principles, step-by-step procedures, and examples of experiment results. For further details, click  Experiment Theory and Contents to explore this apparatus.  

Note: A similar apparatus, LEAI-71, can measure both Hysteresis loop and Curie Temperature of ferrite materials.
