The cow magnet

Stories from Physics for 11-14 14-16 IOP RESOURCES

Cattle may suffer from a condition known as hardware disease caused by the ingestion of foreign bodies. The condition is often treated by encouraging the cow to swallow a cow magnet, a 7 cm rod magnet with an anti-corrosive covering. The magnet remains in the cow’s stomach and collects magnetic foreign bodies, rendering them harmless.
