HTS Dipole Magnet with a Mechanical Energy Transfer in the Magnetic Field [PDF]

, 2022
There were designed and successfully tested at Fermilab several high temperature superconducting (HTS) model magnets for particle accelerators. Some of them worked in a persistent current mode continuously generating magnetic field in the iron dominated magnet gap.

Magnetic dipole moment of a moving electric dipole [PDF]

Am. J. Phys. 80 (2012) 645-647, 2012
The current density of a moving electric dipole is expressed as the sum of polarization and magnetization currents. The magnetic field due to the latter current is that of a magnetic dipole moment that is consistent with the relativistic transformations of the polarization and magnetization of macroscopic electrodynamics.

Rotational tuning of the dipole-dipole interaction in a Bose gas of magnetic atoms [PDF]

Phys. Rev. A 101, 043606 (2020), 2019
We investigate the dynamics of a Bose-Einstein condensate of magnetic atoms in which the dipoles are rotated by an external magnetic field. The time-averaged dipole-dipole interaction between the atoms is effectively tuned by this rotation, however recent experimental and theoretical developments show that dynamic instabilities emerge that may cause ...

Dipole-Magnetic Photo-Recombination in Ultracold Hydrogen Plasma [PDF]

, 2013
The cross section of dipole-magnetic photodisintegration of the negative hydrogen ion has been calculated within the framework of an effective-range theory. The dipole-magnetic cross section of photodetachment within the very narrow range of energy near the process threshold dominates over the dipole-electric one.

Ideal magnetic dipole scattering [PDF]

Phys. Rev. Lett. 118, 173901 (2017), 2017
We introduce the concept of tunable ideal magnetic dipole scattering, where a nonmagnetic nanoparticle scatters lights as a pure magnetic dipole. High refractive index subwavelength nanoparticles usually support both electric and magnetic dipole responses.

Magnetically confined mountains on accreting neutron stars with multipole magnetic fields [PDF]

, 2022
Magnetically confined mountains on accreting neutron stars are candidates for producing continuous gravitational waves. We formulate a magnetically confined mountain on a neutron star with strong multipole magnetic fields and obtain some sequences of numerical solutions.

Unveiling Magnetic Dipole Radiation in Phase-Reversal Leaky-Wave Antennas [PDF]

, 2014
The radiation principle of travelling-wave type phase-reversal antennas is explained in details, unveiling the presence of magnetic-dipole radiation in addition to well-known electric dipole radiation. It is point out that such magnetic dipole radiation is specific to the case of traveling-wave phase-reversal antennas whereas only electric-dipole ...

Acceleration of magnetic dipoles by the sequence of current turns [PDF]

, 2014
Acceleration of magnetic dipoles is carried out by the running gradient of the magnetic field formed while sequent switching on the current turns. Magnetic dipoles, with a diameter of sixty millimeters and full length one meter, are pre-accelerated by using the gas-dynamic method to speed one kilometer per second, corresponding to the injection rate ...

Magnetic dipole-vortex interaction in a bilayer superconductor/soft-magnet heterostructure [PDF]

, 2005
We study the penetration of the nonuniform magnetic field, created by a magnetic dipole with out-of-plane magnetization, into a film heterostructure composed of a type-II superconductor layer and a soft-magnet layer. In the framework of the London approach, the energy of the magnetic dipole-vortex interaction is derived and the critical value of the ...

Phase transitions in dipolar spin-1 Bose gases [PDF]

Phys. Rev. A 84, 013605 (2011), 2011
We study phase transitions in homogeneous spin-1 Bose gases in the presence of long-range magnetic dipole-dipole interactions (DDI). We concentrate on three-dimensional geometries and employ momentum shell renormalization group to study the possible instabilities caused by the dipole-dipole interaction.
