Amy used a magnet to hold one piece of paper on the refrigerator. Later, she tried to use the same magnet to hold a stack of four pieces of paper, and the magnet wouldn't stick to the fridge. Why did this happen?

• The magnet needs glue
• The magnet couldn't hold due to the thickness of the paper
• Paper repels magnets
• A magnet isn't attracted to the refrigerator.
