How is magnetism used to support the theory of seafloor spreading?

The Earth's magnetic field will cause the newly formed seafloor to become magnetic. When the seafloor cools, the magnetism of the sefloor will become permanent.
Then if the Earth's magnetic field changes direction (happens every few hundred thousand years), the seafloor's magnetic field will still point in the direction the magnetic field pointed in when it was formed.
