Why are artificial magnets preferred over the natural magnets?

Artificial magnets are preferred over the natural magnets due to the following reasons :

1. Artificial magnets can be made much stronger than natural magnets.
2. Their magnetic strength can be controlled and increased as needed.
3. They can be made in different shapes: bar, U-shaped, horseshoe, ring, etc. which makes them suitable for specific applications in machines, tools, and devices.
4. Artificial magnets can be easily made in large numbers in factories.
5. Artificial magnets are stronger and more stable over time while natural magnets (like lodestone) are brittle and weaker.
