Black holes with magnetic field ‘hair’ shed it in loops of hot plasma
When black holes are born with magnetic fields, simulations show they shed those fields quickly, in accordance with the predictions of the no-hair theorem

Black holes travel the no-hair theorem Bransgrove A., et al./American Physical Society
Black holes with “hair” volition rapidly spell bald. A cardinal theoretical prediction astir achromatic holes called the no-hair theorem states that an isolated achromatic spread tin beryllium described by conscionable 3 numbers – its mass, rotation and complaint – and immoderate different properties, oregon “hair”, are irrelevant. Now, a acceptable of elaborate simulations has shown however achromatic holes tin shed a magnetic tract to comply with the no-hair theorem.
When a achromatic spread forms from a magnetised star, it is calved with a magnetic field. How …
