A magnetar is a type of neutron star that has an extremely strong magnetic field, thousands of times stronger than that of a typical neutron star. It is believed that these magnetic fields are generated by the rapid rotation of the star and the movement of charged particles within it.
The main difference between a magnetar and a regular neutron star is the strength of their magnetic fields. While a typical neutron star has a magnetic field of about 10^12 Gauss, a magnetar's magnetic field can reach up to 10^15 Gauss. This makes magnetars the most magnetic objects in the universe.
The Tesla of a magnetar is a unit used to measure the strength of its magnetic field. It is equivalent to 10^4 Gauss, so a magnetar's magnetic field can reach up to 10^11 Tesla.
The strong magnetic field of a magnetar can cause intense radiation, making it one of the most dangerous objects in the universe. It can also disrupt the electromagnetic fields of nearby stars and planets, potentially causing havoc on their surfaces.
Yes, there are currently 29 known magnetars in our galaxy, with the closest one being about 14,000 light-years away from Earth. They are thought to be relatively rare, making up only a small percentage of all known neutron stars.
