Question

which actions most likely cause the domains within a material to lose their alignment and become more randomized? check all that apply. heating the material rubbing the material against a magnet passing electricity around the material placing the material in a magnetic field of opposite polarity placing the material near a strong magnet hitting the material

Explanation:

• Heating the material: Thermal energy increases the kinetic energy of the magnetic domains, disrupting their alignment.
• Hitting the material: Mechanical shock can jostle the domains out of their ordered arrangement.
• The other options (rubbing against a magnet, passing electricity around, placing in opposite polarity field, placing near strong magnet) tend to align or re - align domains rather than randomize them. Rubbing against a magnet, placing in a magnetic field (opposite or strong) and passing electricity (which can create a magnetic field) are more likely to induce alignment.

Answer:

• heating the material
• hitting the material
