A magnet is an object that produces a magnetic field, attracting certain materials like iron, nickel, and cobalt. Magnets can be natural, like lodestone, or man-made using materials such as iron or steel. They have two poles—north and south—and when you bring two magnets close, opposite poles attract while like poles repel. Magnets are used in many everyday items, including refrigerators, speakers, compasses, and even in medical machines like MRI scanners. They play an important role in technology, science, and daily life.
MY NOTES:
A magnet is a material that attracts certain metals and has a magnetic field with north and south poles.
What kinds of metals can magnets pull toward them?
What do you think a magnetic field is, even if we can’t see it?
Why do you think magnets have a north and south pole?
What happens when you try to push two south poles together?
Can you name something in your home that uses a magnet?
Do you think all metals stick to magnets? Why and why not?
What’s the difference between a natural magnet and one made by people?
Where do you find natural magnets? Is it possible to find one? Has anyone found one till this time?
