Question

The very strong magnetic field on a neutron star is created by

A) the collapse of the star, which significantly intensifies the original weak magnetic field of the star.
B) differential rotation of the star, with the equator rotating faster than the poles, similar to sunspot formation.
C) a burst of neutrinos produced by the supernova explosion, the equivalent of a very large electrical current flowing for a short time.
D) turbulence in the electrical plasmas during the collapse of the star; the original star would have had no magnetic field.

Answer 1

The very strong magnetic field on a neutron star is created by the collapse of the star, which significantly intensifies the original weak magnetic field of the star. At the surface of the neutron star, protons and electrons are caught up in this spinning field and accelerated nearly to the speed of light. In only two places—the north and south magnetic poles—can the trapped particles escape the strong hold of the magnetic field.

Step-by-step explanation:

The very strong magnetic field on a neutron star is created by the collapse of the star, which significantly intensifies the original weak magnetic field of the star. Any magnetic field that existed in the original star will be highly compressed when the core collapses to a neutron star. At the surface of the neutron star, protons and electrons are caught up in this spinning field and accelerated nearly to the speed of light. In only two places—the north and south magnetic poles—can the trapped particles escape the strong hold of the magnetic field.
