What is a permanent magnet?

• A magnet that produces its own magnetic field and cannot be turned on and off

• A magnet that only becomes magnetic when placed in a magnetic field

• A magnet that loses its magnetism when removed from a magnetic field

• A magnet that is made from iron and nickel

What is a magnetic field?

• The region around a magnet where a force acts on another magnet or on a magnetic material

• The region around a magnet where the magnetic field lines cross each other

• The region around a magnet where the magnetic field is strongest

• The region around a magnet where the magnetic field is weakest

How can a magnetic field be detected?

• Using a magnetic compass

• Using a ruler

• Using a thermometer

• Using a stopwatch

What does the needle of a plotting compass point to?

• The north pole of a magnet

• The south pole of a magnet

• The middle of the magnetic field

• The direction of the magnetic field lines

What do the magnetic field lines never do?

• Cross each other

• Run parallel to each other

• Diverge from each other

• Converge towards each other

What do the closer magnetic field lines indicate?

• A weaker magnetic field

• A stronger magnetic field

• A neutral magnetic field

• A changing magnetic field

What do the arrowheads on the magnetic field lines represent?

• The direction of the magnetic field lines

• The strength of the magnetic field
