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.
