Answer to Question 1

All stars have magnetic fields, and some have fields 100 times stronger than the Sun's. The field is frozen into the ionized gas of the star, and when it collapses into a neutron star, the field is squeezed down, concentrated, and made as much as a billion times stronger. Neutrons have no charge, so they can't anchor a magnetic field, but they are unstable and spontaneously decay into protons and electrons. Those particles are immediately forced by the pressure to merge back into neutrons, but at any moment about 10 percent of the particles in a neutron star and protons and electrons, which have electrical charges so powerful electrical currents can flow in a neutron star and sustain a very strong magnetic field.

Answer to Question 2

False
