Question

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


Which labels belong in the regions marked X and Y?

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

B) X: Repels or attracts other magnets
Y: Attracts iron objects

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

D) X: Attracts or repels iron objects
Y: Attracts other magnets

Answer 1

Labels that belong in regions marked X and Y are;

A) X: Maintains magnetic properties in the presence of another magnet

Y: Is made from magnetically hard ferromagnetic material

Answer 2

Answer:

A) X: Maintains magnetic properties in the presence of another magnet

Y: Is made from magnetically hard ferromagnetic material

Explanation:

Temporary magnets are made up of soft iron. These magnets do not retain magnetism for long and thus, called temporary magnets. These are magnetized when current is passed through it or under the influence of permanent magnet. The domains get aligned in single direction temporarily and can be demagnetized.

Permanent magnets are formed from hard ferromagnetic materials so that these cannot be demagnetized. These magnets retain magnetism. The domains in the permanent magnet are aligned in single direction always.

Thus, the overlapping region X should have: Maintains magnetic properties in the presence of another magnet  and Y: Is made from magnetically hard ferromagnetic material
