Which actions most likely cause the domains within a material to lose their alignment and become more randomized? Check all that apply.

Question

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

Answer 1

The actions that are most likely to cause the domains within a material to lose their alignment and become more randomized are:

1. Heating the material - Heating can increase the thermal energy of the atoms, which can disrupt the alignment of the magnetic domains.

2. Hitting the material - Mechanical impact can cause vibrations and stress within the material, leading to a disruption of the domain alignment.

3. Placing the material in a magnetic field of opposite polarity - Introducing an opposing magnetic field can realign the domains in a way that counteracts their previous alignment.

Therefore, the correct actions to check would be:

• heating the material
• hitting the material
• placing the material in a magnetic field of opposite polarity
