The magnetic field strength on the surface of neutron stars ranges from c. 10 4 to 10 11 tesla (T). [40] These are orders of magnitude higher than in any other object: for comparison, a continuous 16 T field has been achieved in the laboratory and is sufficient to levitate a living frog due to diamagnetic levitation. Variations in magnetic ...
A magnetar is a type of neutron star with an extremely powerful magnetic field (~10 9 to 10 11 T, ~10 13 to 10 15 G). [1] The magnetic-field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays. [2] The existence of magnetars was proposed in 1992 by Robert Duncan and Christopher Thompson. [3]
The magnetic field of a newly born fast-spinning neutron star is so strong (up to 10 8 teslas) that it electromagnetically radiates enough energy to quickly (in a matter of few million years) damp down the star rotation by 100 to 1000 times. Matter falling on a neutron star also has to follow the magnetic field lines, resulting in two hot spots ...
Magnetars are among the universe's most extreme objects - a class of the compact stellar remnants called neutron stars that possess immensely strong magnetic fields. Once in a while, they produce ...
SGR 1806−20 is a magnetar, a type of neutron star with a very powerful magnetic field, that was discovered in 1979 and identified as a soft gamma repeater.SGR 1806−20 is located about 13 kiloparsecs (42,000 light-years) [1] from Earth on the far side of the Milky Way in the constellation of Sagittarius.

An X-ray pulsar is a type of binary star system consisting of a typical star (stellar companion) in orbit around a magnetized neutron star.The magnetic field strength at the surface of the neutron star is typically about 10 8 Tesla, over a trillion times stronger than the strength of the magnetic field measured at the surface of the Earth (60 μT).
The magnetic moment of an object is an intrinsic property and does not change with distance, and thus can be used to measure "how strong" a magnet is. For example, Earth possesses an enormous magnetic moment, however we are very distant from its center and experience only a tiny magnetic flux density (measured in tesla ) on its surface.
