Question

Lidia makes a graphic organizer to compare temporary magnets with permanent magnets.

A venn diagram with 2 intersecting circles. The circle on the left is labeled temporary magnets and the circle on the right is labeled permanent magnets. There is a Y in the permanent magnets circle. There is an X in the intersecting area.
Which labels belong in the regions marked X and Y?

X: Maintains magnetic properties in the presence of another magnet
Y: Is made from magnetically hard ferromagnetic material
X: Repels or attracts other magnets
Y: Attracts iron objects
X: Maintains magnetic properties in the presence of another magnet
Y: Is made from magnetically soft ferromagnetic material
X: Attracts or repels iron objects
Y: Attracts other magnets

Answer 1

Choose the first pair.

X: Maintains magnetic properties in the presence of another magnet
Y: Is made from magnetically hard ferromagnetic material

Reason: Both temporary and permanent magnets are magnetic while near another magnet (temporary ones only while the external field is present), and permanent magnets are made from magnetically hard ferromagnetic materials that retain magnetization.
