Controlling magnetic dipole transition with magnetic plasmonic structures
Optics Letters, 2011A plasmonic structure with double gold patches is proposed for enhancing the spontaneous emission of a magnetic dipole transition through a magnetic hot area. A Purcell factor of nearly 2000 can be obtained at optical frequencies together with a low sensitivity in spatial and spectral mismatches between the light emitter and the resonance mode.

A Multichannel Magnetic Flux Controller for Periodic Magnetizing Conditions
IEEE Transactions on Instrumentation and Measurement, 2012International standards for testing soft magnetic materials require that the magnetic flux density remain sinusoidal with respect to time. Traditionally, this has been achieved via control of the magnetic flux using either analog feedback, which provides real-time control, or iterative digital feedback, which yields more accurate solutions with the ...

Derivative controlled magnetic amplifiers
Electrical Engineering, 1954THE CIRCUIT shown in Fig. 1 is of a low-level fast-response magnetic amplifier, as developed for such low-level signals as are provided by thermocouples, strain gauges, etc. Rectifiers are not included in the input circuit, thus eliminating the restriction which they impose on the minimum signal voltage.

Magnetic fluids - suspensions of magnetic dipoles and their magnetic control
Journal of Physics: Condensed Matter, 2003Suspensions of magnetic nanoparticles exhibit normal liquid behaviour coupled with superparamagnetic properties. This leads to the possibility to control the properties and the flow of these liquids with moderate magnetic fields. The magnetic control enables various experiments in fluid mechanics and gives rise to the development of numerous technical ...

Magnetically controlled insertion of magnetic nanoparticles into membrane model
Biochimica et Biophysica Acta (BBA) - BiomembranesPolysaccharide-coated magnetic nanoparticles (MNPs) have been reported to show potential applications in many biomedical fields. In this report, we have studied the interactions between magnetite (Fe3O4) MNPs functionalized with polysaccharides (diethylamino-ethyl dextran, DEAE-D or chitosan, CHI) with different membranes models by Langmuir isotherms ...

Magnetic control of a tokamak plasma
2008he plasma in a tokamak is magnetically confined through electromagnetic fields generated by a set of poloidal field coils, with feedforward nominal voltages or currents based on an approximate plasma model. Therefore, feedback control is necessary. A good magnetic control is essential for achieving good performance in present devices and expected to be

A Magnet Tip for Controlled Removal of Magnetic Foreign Bodies
American Journal of Ophthalmology, 1978I designed a small diameter magnet tip for intraocular removal of foreign bodies, particularly at the time of vitrectomy. Advantages of the intraocular tip include: (1) reduced likelihood of scraping of the foreign body along the retinal surface while in the magnetic field; (2) reduced chance of incarcerating the retina or choroid, or both, between the
