Most stars spin (albeit is very slowly), but when the star starts to shrink it will speed up due to conservation of angular momentum. Moreover because a neutron star is so very heavy it takes a long time for it to slow down (breaking can occur via magnetic fields for example).
You can test this principle yourself by sitting into an office chair, spreading your arms, and have someone give you a good whirl. You will find that while spinning you will spin faster if you pull your arms inwards and slower if you put them out again.

Why don't all supernova remnants contain pulsars?
A "pulsar" is a rapidly-rotating neutron star, with a core of collapsed matter. The pulsar rotates because the original star rotated. If\\ WHEN a massive star becomes a supernova, the force of the explosion will crush the core of the star into either a neutron star or a black hole, if the original star was massive enough. The angular momentum (the "spin energy") of the original star doesn't disappear; like a figure skater pulling in her arms to spin faster, the neutron star will spin more rapidly because it has collapsed in size. If the neutron star's axis is pointed somewhere close to Earth, we detect the pulsating x-rays and we call it a "pulsar". So to answer the question, all supernova remnants contain either neutron stars or black holes, but they are pulsars only if they spin rapidly.
Could a neutron star break due to a collision?
A neutron star is so dense, that apart from a direct collision from another neutron star, the chances are slim to impossible.
Pulsars cannot be spinning white dwarfs because?
because of the great mass of the star, the gravity of it is very high. So after its death, it actually contracts so tightly that even protons and electrons combine to form neutron and thus results to a star called neutron star. If its previous mass is considerably low, then it could have become a white dwarf
What is spin of particle in physics?
Taking a 'particle' as a proton/ neutron, both of these have spin 1/2. So do all leptons (electrons, neutrinos, etc).
Why do you expect neutron stars to spin rapidly?
This is because of a law called conservation of angular momentum. If a star - which will usually have some rotation, and therefore some rotational momentum - collapses to a size of 20-30 km., angular momentum is conserved. Since the diameter decreases, it must spin faster. (Angular momentum is the product of a quantity called moment of inertia, which depends on the diameter of an object, and angular velocity.)
Why is a neutron star expected to spin rapidly?
All young neutron stars spin rapidly. You might be confused with a pulsar. See related questions.

What would happen to a neutron star with an accretion disk orbiting in a direction opposite to the neutron star's spin?
The neutron star so affected wouldn't really notice. The mass of the neutron star is huge compared to that of the material in the accretion disk. And that matter, when it falls in, wouldn't really "slow" the spin of the star much unless there was a gigantic quantity of matter falling in and/or it acted over a very long period.
A neutron star that rotates rapidly and emits light?
It's called a pulsar. However - ALL young neutron stars emit the said beam. It's only if that beam is detectable on Earth is it called a pulsar. So a Neutron Star and a Pulsar are the same thing. See related questions. but then again they are different.
What is the core of a star called if it is crushed in to a small but very dense object?
"Small but very dense" sounds like the description of a neutron star or "collapsed matter star". Theoretically, a black hole (the only thing more dense) has no physical size at all. So, "neutron star". If the neutron star is spinning rapidly, they are called "pulsars" for the radio-wave pulses that they generate.
What makes a pulsar pulsate?
A neutron star is unimaginably dense. It contains the mass of the Sun, but has that mass squeezed into a ball perhaps 20km (12 1/2 miles) across. Further, neutron stars are so small that they can spin very rapidly, many times per second or faster. When they spin they emit electromagnetic radiation which can appear as flashes from earth. If the magnetic pole of the neutron star is "pointed" [See related link - Pictorial of pulsar] towards Earth, they are called pulsars, as they "pulse" as they spin and can be detected. The flashes produced by the pulsars are detected as the electro magnetic radio waves caught up by the radio telescopes
How do neutron stars differ from other giant stars?
A neutron star is the "end of the line" for a giant star that exploded as a supernova. The material in a neutron star is packed so densely that a chunk of it the size of a cigarette package would weigh thousands of tons. It spins rapidly, at a steady rate (they are sometimes called "radio beacon stars").
What is the meaning of a neutron star?
A neutron star is the remnant of a supernova explosion. Such stars are composed almost entirely of neutrons.A typical neutron star has a mass between 1.35 and about 2.1 solar masses, with a corresponding radius of about 12 kmA neutron star is so dense that one teaspoon (5 millilitres) of its material would have a mass over 5 trillion kg. The force of gravity is so strong that an object falling from just one meter high would take a microsecond to hit the surface but at around 2,000 kilometres per second, or 4.3 million miles per hour.
Could a neutron star break due to a collision?
A neutron star is so dense, that apart from a direct collision from another neutron star, the chances are slim to impossible.
How did neutron stars get its name?
The name "neutron star" some from the fact that the neutron star is mainly composed of neutrons. The gravitational pull of a neutron star is so strong that most matter are crushed into neutrons.
When a collapsed core becomes so dense only neutrons can exist there a what is formed?
A Neutron Star
