Key Takeaways:
- Neutron stars possess extremely strong magnetic fields, the origin of which remains unknown.
- The presence of neutrons in neutron stars does not preclude the existence of strong magnetic fields, as neutrons are charge-neutral.
- Neutron stars are not solely composed of neutrons; other particles are present.
- The composition of neutron stars, particularly the role of charged particles in generating magnetic fields, requires further investigation.

No one knows the exact origin of neutron-star magnetism. The fact that these exotic objects have neutron
in their name should not be cause for concern. While neutrons are
charge-neutral particles — meaning magnetic fields don’t alter their
motions — neutron stars are not made exclusively of these particles.
