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.

Oscillations of a Plasma in a Magnetic Field
Physical Review, 1963The plasma oscillations of a high-temperature and a degenerate plasma, both with and without an applied magnetic field, are discussed using a Green function technique. For the high-temperature plasma in lowest order the results reduce to those obtained via the linearized BoltzmannVlasov equation in the classical limit.

Plasma Oscillations in a Magnetic Field
Journal of the Physical Society of Japan, 1965The small amplitude plasma oscillations of a fully ionized plasma, in which collisions are neglected, in a constant external magnetic field are studied by expanding the velocity distribution about its equilibrium value. Use is made of full set of Maxwell's equation.

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.

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.

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 ...

The Magnetic Torque Oscillator and the Magnetic Piston
The Physics Teacher, 2007A magnet suspended in a uniform magnetic field like that of the Earth can be made to oscillate about the field. The frequency of oscillation depends on the strength (magnetic moment) of the magnet, that of the external field, and the moment of inertia of the magnet.

EPL (Europhysics Letters), 2014
It is shown that the orbit quasi-center of a Bloch electron in a magnetic field is a conserved quantity. This is similar to the conservation of the quasi-momentum for an electron in a periodic potential. When an electric field is turned on, the orbit quasi-center oscillates in a similar way to the oscillations of a Bloch electron without a magnetic ...

Oscillations of Elementary Magnets
Nature, 1947In previous researches discussed in the papers “The Resonance of Magnetons”1 and “Band Distribution in Magnetic Spectra”2, it was established that there may be two types of magnetic dispersion bands. Whereas in the infra-low, acoustic and ultra-acoustic frequency-ranges the magnetic dispersion and absorption bands for ferromagnetic metals can be ...

Oscillating-field misalignment in magnetic resonance
Il Nuovo Cimento B Series 11, 1976The influence of a r.f. field component parallel to the static magnetic field is investigated for magnetic resonance in a two-level system. For the shift of the resonant field accurate analytical expressions are derived. A continued-fraction solution is presented to include relaxation.
