Pulsars in brief :-

Its about the PULSAR ...A pulsar is a neutron star that’s spinning in a special way. (Remember, everything in the universe spins). First you need to know something about poles. The Earth has two north poles and two south poles. Yes, it’s true. One set is because the Earth is spinning: the poles are the tips of the axis that the Earth spins on. The other set is because the Earth has a magnetic field: all magnets have a north side and a south side. On Earth, these two sets of poles are slightly misaligned.In a pulsar, the poles are even more misaligned, so as the star spins, the magnetic field is swung around in circles. When this happens to a neutron star, you get a super-bright beam of light beaming out from the magnetic poles. Since these poles are swinging around, so do the beams of light – just like a lighthouse.
