Magnetars 8 x 1014 Gauss MAGNETIC FIELD A magnetic field is a region near a magnet where other magnets are affected. The is probably caused by its molten iron-nickel core.
Magnetars and Quark stars are both extreme cases of neutron stars, though it appears that they are pretty rare at this point. There is some debate as to whether they actually exist; that perhaps the astronomers got their numbers wrong.

magnetars (NASA Thesaurus) Highly magnetized neutron stars believed to emit quasi-steady x-rays along with bursts of soft gamma rays-- emissions powered by their magnetic energy.

Magnetars form by core-collapse of a massive star in a supernova explosion.
First of all, nobody knows much about magnetars since there existence was only recently suggested and the observational evidence for them is even newer. As far as I know the most likely scenario for their formation is as the remnant from a supernova.
Magnetars are a new and exciting class of objects believed to be pulsars with extreme magnetic fields, a thousand times stronger than those of "ordinary" pulsars.
"Fortunately, there are no magnetars anywhere near the Earth. An explosion like this within a few trillion miles could really ruin our day," said graduate student Yosi Gelfand (CfA), a co-author on one of the papers.
However, it appears that magnetars are only X-ray bright for a short period of time since their pulse periods are clustered between 6 and 12 seconds.
Exactly how magnetars form is uncertain, but one favoured theory is that they evolve from massive stars that possess strong magnetic fields that then become ‘frozen' into the neutron star.
An enormous eruption has found its way to Earth after traveling for many thousands of years across space. ... the dead star belonging to a rare group: the magnetars.
soft gamma-ray repeater (SGR): An object that produces repeated bursts of lower-energy gamma rays; thought to be produced by magnetars.
Accretion-powered pulsars (accounting for most but not all X-ray pulsars), where the gravitational potential energy of accreted matter is the energy source (producing X-rays that are observable from Earth), and Magnetars, ...
As the gas collects on the surface, it becomes hot and emits X-rays. In the second model, which is now strongly supported by observation, AXPs are assumed to be magnetars - neutron stars with ultra-strong magnetic fields.
