The Generation of Magnetic Fields Requires Both a Rapid Rotation

question 4

Multiple Choice

The generation of magnetic fields requires both a rapid rotation and a fluid interior for the flow of currents of charged particles. But neutrons are electrically neutral, so how can a neutron star generate a magnetic field?

• A) Neutrons in neutron degeneracy in a neutron star acquire an electric charge.
• B) Because the neutrons in a neutron star flow through a superconducting medium, they do not need to carry an electric charge in order to constitute a current.
• C) The enormous amounts of friction experienced by degenerate neutrons cause electric charges to build up on their surfaces, like static electricity.
• D) Neutron stars actually contain some protons and electrons, which carry the electric currents.
