Magnetically coupled balance platform

Journal of Medical Engineering & Technology, 2004
The purpose of this study was to develop a new device to assess balance in two planes and then to provide training paradigms for balance abnormalities. Based on the principal of a Biomechanical Ankle Platform System (BAPS) board, the device is different than other devices that are on the market today in that this device allows assessment of balance ...

Magnetically coupled magnet–spring oscillators

European Journal of Physics, 2010
A system of two magnets hung from two vertical springs and oscillating in the hollows of a pair of coils connected in series is a new, interesting and useful example of coupled oscillators. The electromagnetically coupled oscillations of these oscillators are experimentally and theoretically studied.

Geometric approach for coupling enhancement of magnetically coupled coils

IEEE Transactions on Biomedical Engineering, 1996
This 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, 1995
A 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

Magnetically coupled rotors

American Journal of Physics, 2006
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.

Exchange coupling in magnetic heterostructures

Physical Review B, 1993
Many 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.

Permanent magnets applied to magnetic coupling

World Pumps, 2005
Magnetic 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.

Magnetic coupling for a microbalance

Journal of Thermal Analysis, 1991
Balances 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 ...

Coupling heat with magnetization

2015 IEEE Magnetics Conference (INTERMAG), 2015
Spin 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

A magnetically coupled extensometer

Journal of Scientific Instruments, 1964
An extensometer is described which permits measurements through opaque non-magnetic walls with no electrical or mechanical connection to the internal movement. Movements of several inches can be followed with an accuracy to 2 × 10-4 in. through a 0.5 in. thickness of stainless steel.
