Magnets

     We sure have had a lot of fun learning about magnets the last few weeks!  Here is a list of things we have learned.

Do not put magnets up close to stuff that uses electricity.
Magnets are useful.
There is a cow magnet.

Magnets can pick up iron and cobalt.
The earth is a magnet.
Magnets don't stick to copper.


Magnets repel when north and north are together.
I learned that one magnet can move a paperclip through 76 paper plates.
Magnets can attract other magnets.


Some magnets are very strong and some are weak.
Some are used for big things like cars.
They have a north pole and a south pole.


The same poles attract but different poles don't attract.
Magnets stick to batteries.
Magnets push apart when they repel.
