Science fair project information on magnets that you may find useful.
Magnets attract certain materials - such as iron, nickel, cobalt, certain steels and other alloys. They exert an attractive or repulsive force on other magnets. Opposite poles attract, like poles repel.
Magnets have an effect on electrical conductors when the magnet and conductor are moving in relation to each other. Magnets also have an effect on the path taken by electrically charged particles traveling in free space. Based on these effects, magnets transform energy from one form to another, without any permanent loss of their own energy. Examples of magnet functions are mechanical to mechanical - such as attraction and repulsion. Mechanical to electrical - such as generators and microphones. Electrical to mechanical - such as motors, loudspeakers, charged particle deflection. Mechanical to heat - such as eddy current and hysteretic torque devices. Special effects - such as magneto-resistance, Hall effect devices, and magnetic resonance.
Will temperature affect the strength of a magnet? You will find out that colder temperatures will permit the magnetic field strength to increase and hotter temperatures will decrease it somewhat.
The material the permanent magnet is made from has a significant effect on the overall strength of a magnet. The material will also determine how its flux is affected by temperature, and how easily the magnet can be demagnetized by opposing magnetic fields.
You can find out for yourself with experiments such as using a bar magnet and a handful of carpet tacks. Freeze the magnet. Pick up some tacks. Take them off and count them. Record the data. Drop the magnet in boiling water. Use tongs to get it out and hold it with an oven mitt to pick up tacks again. Take them off and count them. Record the data. Compare the data. Repeat a few times. Compare the data from all runs. There is a point called the Curie point or Curie temperature at which the magnetic properties disappear altogether. This temperature varies from material to material
