What is the effect of temperature on the magnetism of ferromagnetic materials? (2022)
Step 1: Understand what ferromagnetic materials are. These are materials that can become magnets, like iron, nickel, and cobalt.
Step 2: Learn about magnetic domains. These are small regions in ferromagnetic materials where the magnetic fields of atoms are aligned in the same direction.
Step 3: Know that temperature affects the movement of atoms. As temperature increases, atoms move more due to thermal energy.
Step 4: Realize that increased movement (thermal agitation) can disrupt the alignment of the magnetic domains.
Step 5: Conclude that when the alignment of magnetic domains is disrupted, the overall magnetism of the material decreases.
