If a magnet is cut in half, each piece will have a

• north end

• south end

• middle section

• north and south pole

Earth has a magnetic field that surrounds it because the core of the Earth has

• spinning molten iron and nickel

• dirt

• oceans and continents

• magnesium

A magnetic field is

• part of the galaxy

• an invisible area around the magnet that has the magnetic force

• invisible lines pointing east to west

• the center of a magnet

What is one rule for attraction of magnets?

• opposite poles repel

• like poles attract

• all poles face north

• opposite poles attract

This magnetic field is ________________ so that the SOUTH POLE of the MAGNETIC FIELD POINTS to Geographic NORTH and the NORTH POLE of the Magnetic Field points to geographic SOUTH.

• reversed

• attracted

• magnified

• attached
