How does different temperatures affect magnets
Transcript of How does different temperatures affect magnets
Organization determines strength
Temperature determines organization
Independent= Room temperature (70), Boiling temperature (150), freezing (29) and dry ice (-109.3)
Controlled= The size of the magnets, amount of iron shaving available to pick up, the pot used, and the area where testing is done
Dependent= The mass of iron shavings that the magnet picks up measured in milligrams.
1. Gather Materials
2. Put magnet into required temperature
3. Before removing, use infrared thermometer to check the temperature
4. Place the magnet on the scale before picking up the iron shavings
5. Use tongs and place magnet 1 inch above the shaving
6. Place magnet on scale and record the mass
7. Take the difference of the data before the iron shavings and after
Trends- The warmer the magnet, the weaker it is
The colder the magnet, the stronger it is
Everything went as expected
Vibration effected strength
Organization effected the strength
Boiling/room temp.= molecules scattered
Freezer/dry ice= molecules lined up
How molecules of a magnet react to temperature
The movement of the molecules in a magnet
Heated-Molecules change directions
Cooled-Molecules are lined up
More Vibration=weaker magnetic field
Room Temperature Area
Heated=Messier organization of molecules
Cooled= molecules all face same way
Higher kinetic energy when heated

The point when a magnet gets too hot and loses magnetism
Molecules bounce frantically
Almost no magnetic field
1043 K (1417.73 degrees Fahrenheit
