Question What are the properties of ferromagnets? Select all that apply: They have permanent magnetic dipole moments. Unpaired electrons in these substances have aligned spins. Unpaired electrons have partially aligned spins. Local magnetic moments are in opposite directions but do not have equal magnitude and so do not cancel out completely They can lose their permanent magnetic dipole when heated.

Solution Steps

The question asks about the properties of ferromagnets and provides multiple statements to choose from.

Ferromagnets are materials that exhibit strong magnetic properties due to the alignment of magnetic moments. Key properties include:

1. They have permanent magnetic dipole moments.
2. Unpaired electrons in these substances have aligned spins.
3. They can lose their permanent magnetic dipole when heated (above the Curie temperature).

• Statement 1: "They have permanent magnetic dipole moments." This is true for ferromagnets.
• Statement 2: "Unpaired electrons in these substances have aligned spins." This is also true for ferromagnets.
• Statement 3: "Unpaired electrons have partially aligned spins. Local magnetic moments are in opposite directions but do not have equal magnitude and so do not cancel out completely." This describes antiferromagnetic or ferrimagnetic materials, not ferromagnets.
• Statement 4: "They can lose their permanent magnetic dipole when heated." This is true for ferromagnets when heated above the Curie temperature.
