We know the substance in the image is magnetized because ___.

• All the domains are at right angles to each other.

• All the domains are aligned.

• All the arrows are drawn in red.

• All the domains are not aligned.

What happens when an object with random magnetic domains is placed into a strong magnetic field?

• It is attracted to the magnetic field

• It aligns with the field and shoots off like superman

• It aligns with the field and usually becomes a temporary magnet itself

• Its domains start moving faster and it gets warmer
