The susceptibility of a magnetic material is `-4*2xx10^-6`. What type of material does it represent?

Explanation

To determine the type of magnetic material based on its susceptibility, we can follow these steps:

### Step 1: Understand the Classification of Magnetic Materials
Magnetic materials are classified into three categories based on their susceptibility (χ):
- **Ferromagnetic materials**: High and positive susceptibility (χ > 0)
- **Paramagnetic materials**: Low and positive susceptibility (χ > 0 but less than ferromagnetic)
- **Diamagnetic materials**: Low and negative susceptibility (χ < 0)
