What is Magnetic Domain?

• Is a region in a magnetic material in which the magnetic fields of the atoms all point in the same direction

• Is a region in a magnetic material in which the magnetic fields of the atoms all point in the different direction

• Every atom has its own magnetic field

• Magnetic effect of random magnetic field

A ___________________ is an object that attracts iron and other material that have magnetic qualities

• Magnet

• Iron

• Steel

• Nickel

Magnetic materials often contain Ferromangtic elements include

• Iron, Nickel, and Cobalt

• Only Iron

• Only Nickel

• Gold

____________ fields an invisible magnetic field surrounds a magnet.

• Magnetic

• Electric

• Neutral

• charge

Materials do not have atoms grouped in magnetic domains

• Non Magnetic Material

• Magnetic Material

• gold

• Iron

Atoms are grouped in magnetic domains. The magnetic field domains point in different directions which cancel each other in

• Magnetic Materials

• Non Magnetic materials

• Magnets

• Plastic

Magnetic field domains line up in the same direction. The magnetic fields of the domains combine to form a single magnetic field around the entire object in

• Magnetic Material

• Magnet

• Non Magnetic Material

• Ferromagnetic

Which system best illustrates attractive forces?

• Y because the magnetic field lines connect to each other

• X because the magnetic field lines repel each other

• Y because the magnetic field lines repel each other

• X because the magnetic field lines connect to each other

Which system would need an external force to move the magnets closer together?

• X, because magnets the magnets are attracting.

• X, because magnets the magnets are repelling.

• Y, because magnets the magnets are repelling.

• Y, because magnets the magnets are attracting.

In which system could you increase the magnetic potential energy by pushing the two magnets closer together ?

• X, because Magnets are attracting

• X, because Magnets are repelling

• X, because Magnets are repelling

• Y, because Magnets are repelling
