What is a magnetar ? Explain the differences between a magnetar and a pulsar​

Answer»

Answer:

A magnetar is a TYPE of neutron star believed to have an EXTREMELY powerful magnetic FIELD (∼109 to 1011 T, ∼1013 to 1015 G). The magnetic field decay powers the emission of high-energy electromagnetic RADIATION, particularly X-rays and gamma rays.

The main difference between them is that pulsars have very strong magnetic fields (10^8-10^12 Gauss or so; Earth's magnetic field is about 0.5 Gauss!) while magnetars have even STRONGER magnetic fields (of order of 10^14-10^15 Gauss).
