There
are many different types of magnets fridge magnets, permanent magnets,
circle magnets, horse magnets and bar magnets. I am going to tell you
about ways humans use magnets how they are made and things magnets won’t
attract to.
There are many different
kinds of magnets. But did you know magnets where not made by humans.
Thousands of years ago the Chinese found a rock that was naturally
magnetic called magnate. So when they were digging it would stick to
their shovels because of a magnetic field. A magnetic field is a field
of magnetic pulls within range of this field anything with iron in it
will stick to the magnet.
Some ways people use
magnets today are to save animals lives like a cow. For example people
use a special type of magnet called a cow magnet to save a cows life.
People also use magnets to play games.
Magnets attract to
different items but not all items. Some items they may not attract to
because it might be a south pole to south Pole or a north pole to north
pole. It won’t stick because it is the same pole is facing the same
pole. Some items still won’t stick because it doesn’t have any iron.
So next time you use a
magnet remember the Chinese found it while digging.
