Necromagnetism was first theorized in the mid-19th century as the possible cause of frogs raining. The hypothesis was that certain kinds of storms caused the electronic elements in flesh (such as the iron in blood, the neurons in the brain) to react with the surrounding water leading to extreme magnetism when the cells were inactive. Essentially that dead fish and frogs became extremely magnetic when certain kinds of storms were overhead causing them to fly through the air for several miles until they became degaussed.
Recent experiments have used this theory to create artificial necromagnets in order to find bodies at sea. This has lead to many levitations of dead things, perhaps the most recent was an experiment involving starlings that had been executed then levitated several miles into Somerset. Necromagnetism is still in it's early stages, although scientists hope to harness this energy in order to explore life after death.
