The Chill Factor

Overview

Objectives/Goals To prove that altering a typical magnet's temperature will affect its magnetic strength. Methods/Materials Using two refrigerator magnets, I will test to see if changing the magnet's temperature through different variables (room temperature, boiling hot temperature, and freezing temperatures), that the colder I get the magnet the stronger its magnetic field will be and therefore be able to pick up more Ball Bearings.

The atoms within the magnetic field of the magnet moved slower and closer together allowing the magnet to pick up more Ball Bearings.
