debgeislerActually, cows aren't the only ruminants to position themselves on the earth's north-south magnetic axis. Deer do it, too.
These scientists wanted to find out if cows could actually *sense* the magnetic fields, or if they oriented based on other environmental cues. So they went and observed cows grazing near high-tension wires, and discovered that they changed orientation.
It is not true that the cows were first fed refrigerator magnets.
