MAGNITI ZE!

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.
