Magnetically coupled magnet–spring oscillators
European Journal of Physics, 2010A 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.

Several ways of partially levitating permanent magnets are described. When displaced from their equilibrium position the magnets oscillate. The field line geometries are deduced theoretically and computationally. The oscillation frequencies are also computed and compared with experimental values.

Journal of Food Science, 2000
Scope of Deliverables: This section reports the effects of magnetic fields on microbial populations. Mechanisms of inactivation and critical process factors are described. Results of microbial testing experiments are controversial. Consistent results concerning the efficacy of this method are needed before its potential use as a food preservation ...

Journal of Physics D: Applied Physics, 2015
The magnetic vortex has sparked the interest of the academic and industrial communities over the last few decades. From their discovery in the 1970s for bubble memory devices to their modern application as radio frequency oscillators, magnetic vortices have been adopted to modern telecommunication and sensor applications.

Magnetic anisotropy oscillations (invited)
Journal of Applied Physics, 1997The magnetic anisotropy in Co films epitaxially grown on Cu(001) is investigated by measuring magneto-optical Kerr hysteresis loops during film growth. As a function of Co thickness the magnetic anisotropy oscillates with a period of 1 monolayer. These oscillations are attributed to the periodic variations of the film morphology alternating between ...

Abstract In magnetism lessons, the demonstrator likely needs an apparatus to visualize the interaction between the Earth’s magnetic field and the magnetic moments of a magnet. So, we present a simple and economical apparatus to fit this purpose and to determine the value of the horizontal component of the Earth’s magnetic field.

The Oscillations of Magnetic Suspensions
Journal of Applied Physics, 1951The oscillations of a magnetic suspension between two equal poles are formulated in terms of a nonlinear ordinary differential equation of the second order that may be integrated in terms of elliptic integrals of the second kind. The case of unequal poles is treated by an analogous procedure involving a Legendre reduction.
