What is Magnetar?

Magnetar is the type of supernova; Specifically, a neutron star with an extremely intense magnetic field. Magnetars are observed by astronomical phenomena such as soft gamma repetitions and anomalous X -ray pulsars. The voltage in the magnetar cortex regularly causes "star covers" and releases electromagnetic radiation in the form of X -rays and creates pulses approximately every ten seconds that astronomers can observe on the ground. Gamma rays are also released at irregular and longer intervals. To make Magnetar, the star must have a quick speed and magnetic field before the collapse. This occurs only in about 1 of 10 cases. Depending on the mass of the star, the neutron star or black hole is left as the rest of the supernova.

If Supergiant Star turns very quickly when it collapses and is not so massive that it collapses into a black hole, intense natural dynamo is formed at InterInera the resulting neutron star. If a neutron star rotates fast enough to keep up with a period of convection (about once every ten milliseconds), the convection currents are able to function around the world and transfer a considerable amount of kinetic energy to the magnetic field. This is the same principle of operation as electrical generators that rotate the curled wire in the presence of a magnetic field to produce electricity. It is assumed that most field building is done in the first 10 seconds when a neutron star is created.

Magnetic magnetic field for magnetar bending does not last long astronomically-only about 10,000 years, then drops to an average neutron star. At this point, their behavior of stars and gamma emissions will cool down. Due to their short life, we see only about nine magnetars in our own galaxy.

The magnetic field generated by Magnetar is really stunning. Its magnetic field is so intense, Magnetar 160,000 km (100,000 miles) could wipe every credit card on Earth. At less than 1,000 km of distance, Magnetar could tear the meat apart due to short magnetic fluctuations in water molecules. Near Magnetar, X -rays and other electromagnetic radiation are divided into two or merger. This phenomenon can be observed in a calcite crystal and is called birefringence.
