Fridge Magnet

Researchers at the University of Cambridge have discovered a metal alloy that actually allows magnets to cool down a fridge than just hold up pictures on the fridge.

“When this alloy is placed in a magnetic field, it gets colder. Karl Sandeman and his co-workers think that their material – a blend of cobalt, manganese, silicon and germanium – could help to usher in a new type of refrigerator that is up to 40 percent more energy-efficient than conventional models.”
