What is the difference between permanent and temporary magnets?

• Temporary magnets can only attract, not repel
• Permanent magnets are stronger than temporary magnets
• Permanent magnets are man-made, temporary magnets occur naturally
• Permanent magnets are always magnetic, temporary magnets loses megnetism
