List two methods of producing magnetic fields.

Explanation

**Step-by-Step Solution:**

1. **Understanding Magnetic Fields**: A magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts.

2. **Method 1: Using Permanent Magnets**:
- Permanent magnets are materials that maintain a persistent magnetic field.
- Common examples include bar magnets, which have a north and south pole.
- When placed in a space, they create a magnetic field around them without the need for an electric current.
