The force on a magnetic dipole
American Journal of Physics, 1988The classical magnetic force on a magnetic dipole depends upon the model for the dipole. The usual electric current loop model for a magnetic dipole leads to the force F=∇(m⋅B) on a magnetic dipole m in a magnetic field B. The separated magnetic charge model for a magnetic dipole leads to the force F=(m⋅∇)B on a magnetic dipole.

Electric and Magnetic Dipole Strength at Low Energy.
Physical Review Letters, 2017A low-energy enhancement of radiative strength functions was deduced from recent experiments in several mass regions of nuclei, which is believed to impact considerably the calculated neutron capture rates.

A recent book rejects the amperian-current model of a magnetic dipole and accepts the magnetic-charge model, because the first model would lead to inconsistencies in the interpretation of Poynting's theorem. It is shown that the inconsistencies are only apparent.

Microwave and Optical Technology Letters, 2005
AbstractA very compact antenna with magnetic dipole radiation properties is presented. It is horizontally polarized HP with low cross polarization level XPR, it has omnidirectional radiation with a very low ripple in the azimuth cut plane. With a compact design (quarter wavelength square) it is suitable for integration into small WLAN devices.

Selective Plasmonic Enhancement of Electric- and Magnetic-Dipole Radiations of Er Ions.
Nano letters (Print), 2016Lanthanoid series are unique in atomic elements. One reason is because they have 4f electronic states forbidding electric-dipole (ED) transitions in vacuum and another reason is because they are very useful in current-day optical technologies such as ...

Magnetic performance of the SSC dipole magnets
IEEE Transactions on Applied Superconductivity, 1993The authors report on the status of the magnetic design of the Superconducting Super Collider (SSC) dipole magnets. A two- and three-dimensional design optimization was performed that included the effects of permeable collar, yoke, cryostat, beam tube, crescent yoke end pieces, cool-down, and Lorentz loads.

The Electric Dipole Moment of a Moving Magnetic Dipole
American Journal of Physics, 1971The fact that a magnetic dipole μ moving with velocity βc has an electric dipole moment p = β×μ/c has made periodic appearance in the literature but the importance of this fact and its general utility have not been given sufficient expression. It is the purpose of this paper to show how to derive the equation p=β×/c and then to use it for a simple ...

Magnetic dipole in a nonuniform magnetic field
European Journal of Physics, 2017The magnetic moment of a permanent magnet is determined from forces acting on the magnet in nonuniform magnetic fields produced by two coaxial current-carrying coils. Therefore, the measurements are performed under well controllable and reproducible conditions. With a data-acquisition system, the experiments can be done in a reasonably short time.

Electric and magnetic dipoles are introduced. The dipole moment for the two cases are defined and used to formulate the interaction between a dipole and various objects. Particularly important is the interaction between two dipoles which are derived for both the electric and the magnetic cases.
