I've always been fascinated with magnets. It's something about their gravity defying action at a distance. I'm not alone if the number of people searching on Google is any measure. Each month over 150,000 people search on the term "magnet". And that's just the tip of the iceberg with thousands more related searches for similar terms.

Below are some of the questions I've been asked about magnets by my students.

• Is Copper Magnetic?
• Is Aluminum Magnetic?
• Is the Sun Magnetic?
• Do magnets work in space?
• Do magnets work underwater?
• What are the strongest magnets you can buy?
