MAGNITIZE!
By: Jeremy Camp
Guiding Question
• Does the temperature of a magnet
affect the time it takes to attract or
repel an object?
My Hypothesis
• I believe that the temperature of a magnet will
affect it’s strength because heating or cooling a
magnet would make it take more time to attract
or repel an object, affecting it’s strength.
Background Information
1. Magnetism was discovered and used over
800 years ago in ancient Greece and China.
2. The north pole on a magnet points towards the
north pole on the earth. This is because they are
both giant magnets and are aligning themselves
together.
3. If you cut a magnet in half, you get 2 smaller
magnets as a result, each with their own
north and south pole.
4. To make a new magnet, take one you already
have and then rub it on a new piece of metal. This
process is called magnetization and will turn any
piece of metal into a magnet.
5. The power of a magnet is measured in Tesla (which was the
name of a scientist who specialized in electricity). Even
though The Earth is massive and is a giant magnet, it is around
1000 times weaker than a small magnet you might have at
home.
6. A magnetic field is an invisible area around every
magnet that attracts metals and other magnets to it.
That is why you can slowly push 2 magnets together
and they will jump to each other, due to them entering
their magnetic fields.
7. The magnetic field made by The Earth is so big and
strong, that it stretches out into space. The Earth is
made from metals and materials like iron, which makes
it just like a smaller magnet you might have at home.
