Mondo Knows Facts

Magnetars possess the strongest magnetic fields in the universe

Their intense magnetic strength is trillions of times stronger than Earth

A magnetar is a specialized type of neutron star with a magnetic field powered by rapid convection during stellar collapse. Measuring up to a quadrillion Gauss, a magnetar's magnetic field is strong enough to dissolve atomic electron clouds of any matter entering within a thousand kilometres of its surface.
