magnetic domains

What happens when two magnets are brought close to each other?

• Nothing happens

• They create an electric field

• They attract or repel each other

• They become demagnetized

What are magnetic domains?

• Regions where magnetic fields of atoms are aligned

• Particles that create electric fields

• The poles of a magnet

• Tiny magnets that can be seen with the naked eye

How many atoms can be within a single magnetic domain?

• Hundreds

• Thousands

• Billions

• Millions

What distinguishes a magnetized piece of iron from an unmagnetized one?

• Its color

• Its weight

• The alignment of its magnetic domains

• Its temperature

What is the state of domains in an unmagnetized material?

• Aligned in one direction

• Aligned in two directions

• Concentrated at one end

• Randomly oriented

What does the direction of arrows inside a magnetized material indicate?

• The strength of the magnetic field

• The temperature of the material

• The direction towards the north pole

• The location of the magnetic field

How can an unmagnetized piece of steel be magnetized?

• By aligning its magnetic domains

• By breaking it into smaller pieces

• By painting it

• By cooling it down

Can magnetic materials be in an unmagnetized state?

• Yes, always

• No, never

• Yes, but only temporarily

• Yes, if they are not exposed to a magnetic field

What is the primary reason a material becomes magnetized?

• Due to its chemical composition

• Because of its temperature

• Through the alignment of magnetic domains

• By applying an electric current
