| COMMENTARY | Electromagnets are put in the ground under houses and other buildings that have magnets attached to their bottom. Usually the south and north poles face each other so that the buildings stick to the ground, but when an earthquake strikes, two north poles face each other automatically and the buildings float above the ground. |
