Take any old bar magnet and cut it in half and it will still have a North and a South pole.
Keep cutting, you’ll never end up with a single North or South pole.
Whoever discovered a fundamental magnetic charge, like a single pole, would likely win the Nobel Prize.
A team of physicists at the Institute of Science and Technology Austria haven’t done quite that, but they’ve realised that some collections of molecules behave as if they were “magnetic monpoles,” magnets with only one pole.
This has been done for 20 years.
The main focus was to study the property of molecules,” Mikhail Lemeshko from IST Austria told Gizmodo.
