... magnetic phase diagram of (Mg0.75,Fe0.25)O is reported in Fig. 4. The diagram shows regions of the HS paramagnetic and antiferromagnetic phases at 0-50 GPa, and the LS diamagnetic phase above 56 GPa. The pressure-dependent Néel temperatures (the dash blue line in Fig. 4) in the region 0 < P < 50 GPa ...

Simulation of Charged Particle Motion in Jupiter`s Magnetosphere
... Particle orbits in the Jovian field can be classified roughly into three categories: bounded, transient, and stochastic. Figures 2.0–2.1 show a transient orbit that characteristically follows the expected dipolar orbit until it hits the current disc. Once inside, it bounces around unpredictably, but ...

magnetic circuit design
... This means that when the length is shorter and the magnet area and permeability are greater, the permeance is greater. Conversely the reluctance is reduced. The total magnetic circuit permeance Pt is considered as a total of any air gap permeance Pg defined as a reciprocal of magnetic reluctance in ...

Experiment: Testing A Variety of Objects for Magnetic Attraction
... On a bar magnet the poles are at either end of the magnet. Poles occur in pairs of equal strength. One pole - North seeking pole - N pole- pointing roughly to the Earth's North pole. Other pole - South - S pole Like poles repel Unlike poles attract Force between magnetic poles decreases as the ...

Can the Imaginary Part of Permeability be Negative?
... Therefore, the possibility that ⬙共兲 can be negative is, theoretically, open. Of course, it is not possible to make a more definitive statement in the absence of empirical evidence. The arguments presented above suggest that it is not unreasonable to search experimentally for situations in which ⬙ ...

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.
