Geometric approach for coupling enhancement of magnetically coupled coils
IEEE Transactions on Biomedical Engineering, 1996This paper presents a geometric approach for the enhancement of the coupling coefficient between two magnetically coupled coils. It is demonstrated that the coupling coefficient can be considerably enhanced, if the turns of the coils are not concentrated at the circumferences, but distributed across the diameters. For analysis, each of the two coils is

Theory of interlayer magnetic coupling
Physical Review B, 1995A theory of interlayer exchange coupling is presented. A detailed and comprehensive discussion of the various aspects of the problem is given. The interlayer exchange coupling is described in terms of quantum interferences due to confinement in ultrathin layers. This approach provides both a physically transparent picture of the coupling mechanism, and

Magnetic coupling for a microbalance
Journal of Thermal Analysis, 1991Balances utilising the principle of free magnetic suspension can be very useful for thermogravimetric experiments, where aggressive atmospheres and high pressures are applied. Magnetic coupling systems with automatically controlled attraction can be used for direct conversion of weight into an electric signal or for the separation of object and beam ...

Exchange coupling in magnetic heterostructures
Physical Review B, 1993Many structures consisting of magnetic layers separated by a nonmagnetic spacer layer show an oscillatory exchange coupling. This behavior is explained in terms of a simple model that shows that the Fermi surface of the spacer-layer material is responsible for the oscillatory coupling.

A system with intriguing oscillatory behavior is created using small magnets fixed to the edges of parallel rotating structures. Under certain conditions a system of two rotors will exchange velocities repeatedly in a manner similar to many coupled-oscillator systems, but without oscillations in their position.

Permanent magnets applied to magnetic coupling
World Pumps, 2005Magnetic coupling has been widely used in modern industrial production and scientific experiments for its outstanding advantage of conveying power without vibration, which is quite superior to that of mechanical coupling.

Coupling heat with magnetization
2015 IEEE Magnetics Conference (INTERMAG), 2015Spin caloritronics[1], an emerging branch of spintronics, studying the addition of thermal effects to the electrical and magnetic properties of nanostructures, has recently seen a rapid development. It has been predicted by Hatami et al. [2] that a heat current can exert a spin torque on the magnetization in a nanostructure, analogous to the well-known

9th International Conference on Electrical Machines and Drives, 1999
Eddy current couplings using embedded magnet excitation are now commercially available offering key benefits in applications such as large pumps, compressors and conveyors. The paper describes a linear field model based upon 'layer theory' that has been used to assist in the development and optimisation of a range of eddy current couplings.

The circuit elements in circuits, we analyzed thus far, are conductively coupled. Conductors are used to connect elements. Circuit elements can also be connected through magnetic fields, called magnetically coupled. An inductor is basically a conducting coil.
