Highly unlikely. If the Earth's magnetic field resulted from surface
concentrations, the magnetic field would be far more "lumpy" than it
is. Moreover, Earth is not the only planet in the solar system to
exhibit a magnetic field. Jupiter, Saturn, Uranus, and Neptune also
do.

A far more consistent explanation is that a planet's magnetic field
arises from the rotation of a conducting fluid in its interior.
