Hammering strengthens the magnetic properties.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement we need to evaluate is "Hammering strengthens the magnetic properties."

2. **Identifying the Effect of Hammering on Magnets**: When a magnet is hammered, it is subjected to mechanical stress. This stress can disrupt the alignment of the magnetic domains within the magnet.

3. **Magnetic Domains**: Magnets are made up of tiny regions called magnetic domains. In a strong magnet, these domains are aligned in the same direction, which contributes to the magnet's overall strength.

4. **Effect of Hammering**: When you hammer a magnet, the mechanical force can cause these domains to misalign. As a result, the magnet's strength decreases.

5. **Conclusion**: Therefore, the statement "Hammering strengthens the magnetic properties" is false. Instead, hammering weakens the magnetic properties of the magnet.

6. **Final Answer**: The statement is false.
