How do magnets work in refrigerator?
The magnetic field created by the fridge magnet aligns the spins of unpaired electrons in metal atoms in the fridge in such a way that the magnet and the fridge door are attracted to each other; this force keeps the magnet stuck to the fridge.
How do you teach kids about magnets?
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. Categorize the objects into two piles: those that react to the magnet and those that don’t. Discuss what the pile that reacted to the magnets have in common.
Where is a magnet used in your refrigerator?
Your refrigerator uses a magnetic strip in its door. All refrigerators must seal to lock out the warm air and keep cool air inside. A magnet is what allows these seals to be so effective. The magnetic strip runs the length and width of the refrigerator and freezer door.
What is a refrigerator magnet used for?
A refrigerator magnet or fridge magnet is a small magnet, often attached to an artistic or whimsical ornament, which may be used to post items such as shopping lists, child art or reminders on a refrigerator door, or which simply serves as decoration.
Why is fridge magnetic?
Fridges have magnetic doors. This is a fact of the modern age. They are there to keep your food fresh and out of your cat’s mouth, right? It was decided that if weak magnetic strips were used on fridge doors they would be able to create an air-proof seal, but would open from the inside with a light push.
How do you explain magnets to preschoolers?
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.
What is in a fridge magnet?
A refrigerator magnet is made of powdered ferrite (iron rust) and a liquid binding agent of plastic or rubber. The two are heated, mixed together, and poured into a sheet mold which is then exposed to a strong magnetic field.

What’s the best way to teach kids about magnets?
Take a look through your drawers and around your home and classroom for interesting objects. Make sure to get a variety of both magnetic and non-magnetic objects. You can even add a few that are not totally magnetic but have a magnetic part to encourage observation and problem solving skills.
Which is the best science activity for kids?

Why do magnets stick together from a distance?
Exploring magnets encourages all of these. Magnetism is an attraction that two items have making them stick together! Even from a distance magnets can find each other because of their magnetic field. A magnetic field is an invisible area all around the magnet that attracts other magnetic material.
