Question: what is the difference between a simple neutron star and a pulsar?
Answer: Neutron stars emit high-energy beams at its North and South magnetic poles, which is usually made from material from a companion star. If these beams are pointed at Earth, as the Neutron star rotates, they seem to pulse. ... So, all Pulsars are Neutron stars, but not all Neutron stars are Pulsars.
