Crackling noise emitted in systems as diverse as candy wrappers and earthquakes show strikingly similar behaviour, but how it is influenced by the details of these systems is unclear. A study that identifies the microscopic origin of unexplained asymmetries in the noise emitted by a magnet could provide some answers.
