Magnetization of iron is a ____________ change. (physical, chemical, irreversible).

Explanation

To determine the type of change that magnetization of iron represents, we can follow these steps:

### Step 1: Understand Magnetization
Magnetization is the process where iron becomes magnetized when it is exposed to a magnetic field. This means that the iron can attract other magnetic materials.

**Hint:** Think about what happens to the properties of iron when it is magnetized.

### Step 2: Identify the Type of Change
