A magnet is a rock or a piece of metal that can pull certain types of metal toward itself. The force of magnets, called magnetism, is a basic force of nature, like electricity and gravity. Magnetism works over a distance. This means that
a magnet does not have to be touching an object to pull it
.
How do you introduce magnets to preschoolers?
Let your preschoolers pick some of these.
Sit down at a plastic or wooden table with the magnets and the objects
. Experiment with how the magnets interact with each other. Explain that a magnet has two sides, called positive and negative, and that opposites pull together.

How do you introduce magnets to kids?
For younger children, consider going
on a ‘magnet hunt’
. Give them a magnet (a horseshoe or bar magnet will work well, if you have one), and have them try to ‘capture’ other objects, using the magnet. For example, they might experiment on paper clips, coins, an eraser, nails, aluminum foil, a plastic pen, and a pencil.
What are 5 facts about magnets?

What can children learn from magnet?
You can use magnet play to help children
increase their language skills
by teaching them new magnet-related words, names, and shapes. Magnet play can also help children develop their coordination skills, increase their fine motor skills, and learn a variety of problem-solving skills.
What are the 4 types of magnets?
Permanent Magnets. There are typically four categories of permanent magnets:
neodymium iron boron (NdFeB), samarium cobalt
How do magnets work kindergarten?
Magnets have both a North and a South pole. If you place the unlike poles of two magnets near each other,
they will stick together
(attract). When you place like poles of two magnets near each, they push each other away (repel).
What makes two magnets attract?
When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. … Unlike-poles attract: When a north pole and south pole point together,
the arrows point in the SAME direction so the field lines can join up and the magnets pull together
(attract).
What do magnets attract?
Specifically, they stick to
ferromagnetic materials like iron and things that contain iron
, such as steel. This includes everything from your car’s steel body to your refrigerator door. They’re also attracted to nickel and cobalt, and a few other rare-earth elements.
What is the purpose of magnet?
Magnets are
used to make a tight seal on the doors to refrigerators and freezers
. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people’s bodies.
How long do magnets last?
How long does a permanent magnet last? A permanent magnet, if kept and used in optimum working conditions, will
keep its magnetism for years and years
. For example, it is estimated that a neodymium magnet loses approximately 5% of its magnetism every 100 years.
