Abstract
IN a recent communication Hide and Malin1 studied the similarities in the variations of Earth's gravitational and magnetic fields in an effort to determine the undulations on the core-mantle interface. These undulations, if present, can produce significant distortions in the geomagnetic field as it is observed on the Earth's surface2,3. These bumps will also distort the gravitational field.
