Neutron Star

How can we see a neutron star?

Attached is the NASA description of a neutron star.

There are conflicting claims whether they can emit light or X-rays, so probably they can do one or the other.
Since the neutron star is claimed to contain only densely packed neutrons there are no electrical charges available (protons or electrons) to generate an electromagnetic force.

from below:

1)
'Many neutron stars are likely undetectable because 'they simply do not emit enough radiation. '

The problem is apparently their energy output is too weak not that there is none. How is there any from just neutrons?

2)
'More often, though, neutron stars are found spinning wildly with extreme magnetic fields as pulsars or magnetars. In binary systems, some neutron stars can be found accreting materials from their companions, emitting electromagnetic radiation powered by the gravitational energy of the accreting material. Below we introduce two general classes of non-quiet neutron star – pulsars and magnetars.'

Magnetic fields are generated by an electric current but there can be done with just dense neutrons. How an extreme magnetic field can arise when one is impossible is unclear. I must have missed something in physics class to learn how gravity can be an energy source to emit electromagnetic energy.

3)
'
Most neutron stars are observed as pulsars. Pulsars are rotating neutron stars observed to have pulses of radiation at very regular intervals that typically range from milliseconds to seconds. Pulsars have very strong magnetic fields which funnel jets of particles out along the two magnetic poles. These accelerated particles produce very powerful beams of light. Often, the magnetic field is not aligned with the spin axis, so those beams of particles and light are swept around as the star rotates. When the beam crosses our line-of-sight, we see a pulse – in other words, we see pulsars turn on and off as the beam sweeps over Earth.'

In this scenario a star composed of only neutrons can generate jets of particles so if the jet is not neutrons what are these particles? What force is available to generate the motion for this jet?

X-rays are possible when charged particles are accelerated in a magnetic field, or  synchrotron radiation.
With a neutron star and even with an accretion disk there is no identified electric current - but there must be one present when X-rays are detected.

The magnetic field poles are the proposed light source so this source must be this ambiguous jet of particles. It cannot be neutrons.

Synchrotron radiation can cover a broad spectrum.

The accepted description for a neutron star is incapable of explaining the observations of the object. There must be an electric current present to generate whatever electromagnetic radiation is observed but a neutron star cannot generate nor support an electric current.

A neutron star requires electromagnetic behaviors to match observations but the accepted explanation for a neutron star provides no source for those behaviors.

A neutron star must be like other stars where charges are present, as well as the accompanying electromagnetic forces.
