Computer simulations by the researchers have revealed that these hot zones reduce the on the core—and this causes regional or localized changes to the properties of the magnetic field.

Computer simulations further showed that a monopole’s charge would fully flip – from positive to negative, say – if it moved through the Alice ring.
