Magnetism - Reocities
... All magnetic materials are made up of tiny regions called domains. These domains have north and south poles. Each domain is a magnet in itself. In an ordinary piece of iron, domains are oriented randomly. The magnetic effect is absent. But in a magnet, those domains are properly oriented. Therefore ...

Solar Activity and Classical Physics
... Before going into future probing of the mysteries of the Sun, it is well to appreciate what has been accomplished so far in understanding the structure and behavior of a star like the Sun. The “classical” Sun is a self-gravitating ball of gas with a central thermonuclear core, an outflow of heat to ...

Neutron magnetic moment
The neutron magnetic moment is the intrinsic magnetic dipole moment of the neutron, symbol μn. Protons and neutrons, both nucleons, comprise the nucleus of atoms, and both nucleons behave as small magnets whose strengths are measured by their magnetic moments. The neutron interacts with normal matter primarily through the nuclear force and through its magnetic moment. The neutron's magnetic moment is exploited to probe the atomic structure of materials using scattering methods and to manipulate the properties of neutron beams in particle accelerators. The neutron was determined to have a magnetic moment by indirect methods in the mid 1930s. Luis Alvarez and Felix Bloch made the first accurate, direct measurement of the neutron's magnetic moment in 1940. The existence of the neutron's magnetic moment indicates the neutron is not an elementary particle. For an elementary particle to have an intrinsic magnetic moment, it must have both spin and electric charge. The neutron has spin 1/2 ħ, but it has no net charge. The existence of the neutron's magnetic moment was puzzling and defied a correct explanation until the quark model for particles was developed in the 1960s. The neutron is composed of three quarks, and the magnetic moments of these elementary particles combine to give the neutron its magnetic moment.
