• Some magnets are found naturally in the earth. Lodestones are natural magnets made from a substance called magnetite.
• Other magnets are made from magnetic materials like steel, iron, nickel and cobalt. Magnets can also be made from copper and aluminum.
• Breakfast cereal often contains iron. Some cereals contain enough iron that it’s pieces are attracted to a magnet.
• Did you know that you can easily turn common items like paperclips and iron nails into a temporary magnets? A temporary magnet acts like a permanent magnet when it is within a strong magnetic field. However, a temporary magnet looses it’s magnetism when the magnetic field disappears.
• The ends of a compass needle always point toward earth’s north and south magnetic poles.
• Magnets can be found in many common household items such as telephones, computers, stereos, refrigerators, TV’s and VCR’s.
• Over 80% of all households in the US have magnets on their refrigerator. Are you displaying your kids artwork on your fridge right now?

• A magnet always has north and south poles. Cutting a magnet in half makes two magnets, each with two poles.
• Hammering a magnet will cause it to loose its magnetic properties. Heating a magnet is another way to take away it’s magnetic properties. This is because the molecules lose their north-south alignment and get arranged in random directions.
• The Earth of one big magnet. This is because the Earths solid iron core is surrounded hot molten iron that is moving around it. This churning iron creates an electric current that generates a magnetic field around the planet.
• The Earth’s magnetic field is 1,000 times weaker than a typical bar magnet.
• Did you know earth’s magnetic poles are always moving? The poles move about 5 miles (40 kilometers) each year.
