Cold vs Heat vs Room

Temperature

There are four different types of temperature scales that I researched. The Absolute scale, Fahrenheit scale, Celsius scale, and the Kelvin

scale. The Celsius scale is also known as the Centigrade Temperature Scale. When a metal passes through the magnetic field, the electrons start to

line up to the electric current, the part of the metal closer to the field

becomes the South Pole and the other end of the magnet becomes the North Pole.

RESEARCH

How does a magnet’s temperature

affect its strength?

PROBLEM STATEMENT

If the magnet’s strength depends onIts temperature, then I hypothesis that the

cold temperature magnet will have a strongermagnetic force therefore its strength will

be the strongest out of the rest.

HYPOTHESIS

The temperature of the magnets

INDEPENDENT

VARIABLE:

The amount of paper clips themagnets have magnetized

DEPENDENTVARIABLE

The time the magnet is left in the freezer and in the boiling water(5 min)

The time for the magnet to collect the paper clips(1 min)

The heater Type and shape of magnet Same type of paper clips

Number of paper clips The timer

CONSTANTVARIABLES

3 Magnets 1 Freezer 1 Timer 1 heater

12 Paper clips Safety gloves

A bowl A dry towel cloth

A tea kettle Pencil & Paper

MATERIALS

1. Grab all materials2. Put one magnet in the freezer for 5 minutes

3. While your waiting for the magnet in the freezer you layout the 12 paper clips on a table

4. Take the magnet out and start the timer until it reaches 1 minute, during that one minute you collect the paper clips

with the magnet5. Record how many paper clips the magnet has magnetized,

repeat steps 2-5 two more times to get an accurate average.

6. You grab the tea kettle with water and you boil the water, use your safety gloves to carefully put the water in the bowl7. Lay the magnet inside the water and leave it in for 5

minutes, then take the towel cloth and dry the magnet8. Then, do steps 4& 5

PROCEDURES

9. Grab the room temperature magnet, start collecting the paper clips

10. Record how many paper clips the magnet magnetized, repeat steps 9-10 two more times, then find the average

with the magnet until the timer reaches 1 minute

PROCEDURES

`

The cold magnet was resulted stronger than the other temperature magnets.

The cold magnet resulted with an average of 9.33 , the hot magnet

resulted with an average of 7.33, and the room temperature magnet

resulted with an average of 7. The warm magnet wasn’t as strong as the

cold magnet. Same with the room temperature magnet.

Results

My hypothesis was correct, the cold temperature magnet’s strength would

be the strongest. This experiment would benefit man-kind by using colder

magnets to get stronger results. For example: a scientist wanted to test his magnets to find out which can pull a

metallic cube from a table, he can use my answer to make his prediction with confidence. Magnets can probably be

used in the future to replace glue.
