Introduction

Magnetic hysteresis loop and magnetization curve present the basic magnetic characteristics of magnetic materials. A large number of ferromagnetic materials with various properties have been applied in industry, transportation, communications, electricity and electronics, and other fields.

 

This experimental apparatus is designed with the following features:

 

1. Use of a high-precision digital Tesla meter for high measurement accuracy

2. Demagnetizing process at the time of measuring DC magnetic properties of materials

3. Measurement of magnetic field intensity distribution in a gap

4. Three different magnetic materials provided as samples

 

Using this apparatus, the following experiments can be performed:

 

1. Acquire the relationship of magnetic induction intensity B and position X in a sample using a digital Tesla meter

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

3. Learn how to demagnetize a magnetic sample, measure the start magnetization curve and magnetic hysteresis

4. Learn how to apply Ampere's circuit law in magnetic measurement
