Magnetic resonance measurements of hyperfine structure using optical pumping Contents
... When the interaction between the external field and the atom is stronger than the hyperfine interaction, as in the case of a strong external field (in the order of magnitude 1 T), Hm is applied as a perturbation before Hhfs . This is the Paschen-Back effect for the hyperfine structure and the first ...

... Actually the Leo Stick is just a simple generator. Anytime the amount of magnetic field changes through the area of a coil, that causes an electrical current to flow in the coil. What if we arrange the Magnets and coils around in a circle then we can turn a crank, and make electricity over and over ...

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.
