... • Does this decaying magnetic field induce an emf in the loop itself? A: Yes B: No. • Yes it does! The induced emf will be such as to produce some magnetic field to replace that which is disappearing—that is, in this case it will generate field going in through the loop, so the current will be as sh ...

... This is a drag-like force. It thus seems that when moving an object in a static magnetic field, the magnetic fields act as if it were fluid. Hence, the static electric and magnetic fields behave as fluid of massive photons. As a result a longitudinal viscous force would act on the moving charge. Bec ...

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.
