Well magnetar is a star with a Strong magnetic field so i say it could pretty much pull something off Earth if it came close from One quadrillion miles (1,000,000,000,000,000 miles) away.

All "pulsars" are neutron stars - it's just "we" term pulsars as neutron stars who's orientation towards us shows the beam of electromagnetic radiation.

Other neutron stars who's orientation, do not point towards us are not called pulsars, although they exhibit the same characteristics.

No. A neutron star is quite small, generally only a few miles across. A nebula is light years across.

Whether a star will become a neutron star is determined by its mass. Generally, stars that are more than 8 solar masses (have a mass that is more than 8 times that of our Sun), but are less than 15 solar masses will become neutron stars when they die.

In a supernova explosion, the core of the star typically, we believe (because we've never had an actual example to study) collapse into a black hole. There may be some cases in which the core is "only" compressed to neutron-star density, but our understanding of the mathematics of extreme gravity and pressure is a little weak around the edges there.

Because of it's initial high temperature it is not even on the diagram, but far off to the left of the diagram.

Observations show that neutron stars spin very rapidly.

As far as we know, the sun will never become a neutron star. it will eventually become a Red Giant and then it will eventually become a white dwarf

The fastest spinning neutron star that we've found so far is XTE J1739-285, which spins 1122 times every second. It was found by NASA's Rossi X-Ray Timing Explorer (RXTE) satellite. The most rapidly spinning pulsar, however, remains PSR J1748 2446ad, which spins 716 times a second. This pulsar was found by a team at Montreal's McGill University.

No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.

Mostly neutron stars are detected with radio telescopes. Some can actually be seen with optical telescopes, and these are all optical pulsars.

Neutron stars were discovered because they are radio sources. The first star known to be a neutron star was the Crab Nebula neutron star, or Crab Pulsar, which was discovered to be a neutron star because of its radio emissions in 1965. Its apparent magnitude is 16.5. This puts it beyond the abilities of most amateur telescopes.

A neutron star is composed almost entirely of neutrons.

They are supported against further collapse by quantum degeneracy pressure due to the Pauli exclusion principle. This principle states "that no two neutrons (or any other fermionic particles) can occupy the same place and quantum state simultaneously."

All of the above.

The most immense gravity for it's size of any single object in the universe. If it had been a slightly larger star before it went supernova and wound up as a neutron star, it would have collapsed into a black hole - where not even light could escape it's gravity.

What gives off, the injector pluse? Do you mean, where do the pluse signals, that trigger the injectors, come from? The EMC (engine managment computer) usually handles this, after receiving bizillions of sensor readings, from every related sensor, involved in the process.

A neutron star is already a dead star it can produce no more energy, although massively dense it will just continue to radiate its energy out into space until there is nothing left. There is an alternative ending for a Neutron Star and that is, if it was a part of a binary system or had enough mass collect on it could collapse further to create a Black Hole.
