Das Modell zeigt, wie drehende Neutronensterne enorme Magnetfelder erhalten

Some neutron stars have magnetic fields so strong that they would be able to wipe the information from all the credit cards on earth if the star were sitting halfway between us and the moon. Part of the reason why their fields are so powerful, is that the magnetic fields of the progenitor star are squashed down when the supernova collapse happens. Squashed magnetic fields grow much stronger because of that squashing. Furthermore, magnetic fields are built by dynamo mechanisms, and that is what a neutron star is. It may be rotating hundreds of times a second and it has charged particles in its inners, so magnetic fields are powered.
