Astronomers have discovered a supermassive black hole with an inverted magnetic field

The fascination surrounding black holes is something that fascinates every space enthusiast. The physics behind it has occupied scientists for decades. These mysterious space elements are known as powerful cosmic engines because they provide the energy for quasars and active galaxy cores. We may discuss black hole magnetic fields, but black holes do not have their own magnetic field. The dense plasma that surrounds the black hole as an accretion disk results in a magnetic field around these black holes. Observing the galaxy 1ES 1927+654, located 239 million light-years away, scientists observed an abrupt change in brightness around the galaxy’s massive black hole.

This was attributed to the sudden change in the black hole’s magnetic field. While stars are known for their magnetic reversal, black holes are believed not to be the case. Our sun reverses its magnetic field every 11 years. But a black hole is said to be more stable in that regard.

The plasma of a black hole swirls and the charged particles it contains, together with a magnetic field, generate an electric current. The direction of plasma flow does not change spontaneously. Therefore, a black hole’s magnetic field is believed to be fairly stable. But this latest observation of a black hole’s magnetic reversal has stunned scientists.

A report in Science Alert states that scientists observed this galaxy in 2018 through an automated sky survey. Scientists observed that the galaxy had brightened 100 times in visible light. Swift Observatory has captured its glow in X-rays and ultraviolet rays to look beyond visible light. Data from archival observations showed that the galaxy had started to brighten towards the end of 2017.

Initially, scientists believed that the increased brightness was caused by a star flying past the galaxy’s black hole. But this event would have caused a disturbance that would have torn the star apart. Since this was not the case, scientists continued their study of the galactic flare.

After examining changes across the spectrum of light, scientists discovered an abrupt drop in X-rays. X-rays are the result of spiraling charged particles in an intense magnetic field. This change in X-rays indicated a sudden change in the magnetic field.

The researchers suspect that when a black hole accretion disk undergoes magnetic reversal, the magnetic field at the outer edges of the disk weakens. After the reversal is complete, the hard drive will return to its original state. Astronomers have discovered a supermassive black hole with an inverted magnetic field
