How Do Magnetars Generate the Strongest Magnetic Fields in the Universe?
磁星如何产生宇宙中最强的磁场？
-
Magnetars are neutron stars with magnetic fields up to one thousand trillion times Earth’s.
-
Their extreme magnetism comes from rapid rotation combined with intense convection in super-dense cores.
-
When massive stars collapse, their magnetic fields get compressed and amplified dramatically.
-
Dynamo action—driven by swirling, electrically conductive neutrons—boosts field strength further.
-
These fields are so powerful they distort atoms and affect light polarization across vast distances.
-
Magnetars occasionally release giant flares, emitting more energy in 0.1 seconds than the Sun does in 100,000 years.
-
Unlike regular pulsars, magnetars spin slower and emit mostly X-rays and gamma rays.
-
Their crusts can crack under magnetic stress, causing starquakes that shake the entire star.
-
Only about 30 confirmed magnetars exist in our galaxy, making them rare but vital cosmic laboratories.
-
Studying them helps test physics under conditions impossible to recreate on Earth.
