Experimental evidence for magnetorotational instability in a helical magnetic field
Frank Stefani, Thomas Gundrum, Gunter Gerbeth +4
A recent paper [R. Hollerbach and G. Rudiger, Phys. Rev. Lett. 95, 124501 (2005)] has shown that the threshold for the onset of the magnetorotational instability (MRI) in a Taylor-…
Boundary-integral method for poloidal axisymmetric AC magnetic fields
J. Priede, G. Gerbeth
This paper presents a boundary-integral equation (BIE) method for the calculation of poloidal axisymmetric magnetic fields applicable in a wide range of ac frequencies. The method…
Stability of an electromagnetically levitated spherical sample in a set of coaxial circular loops
J. Priede, G. Gerbeth
This paper presents a theoretical study of oscillatory and rotational instabilities of a solid spherical body, levitated electromagnetically in axisymmetric coils made of coaxial c…
Paradox of inductionless magnetorotational instability in a Taylor-Couette flow with a helical magnetic field
J. Priede, I. Grants, G. Gerbeth
We consider the magnetorotational instability (MRI) of a hydrodynamically stable Taylor-Couette flow with a helical external magnetic field in the inductionless approximation defin…
A paradigmatic model of Earth's magnetic field reversals
F. Stefani, G. Gerbeth, U. Guenther
The irregular polarity reversals of the Earth's magnetic field have attracted much interest during the last decades. Despite the fact that recent numerical simulations of the geody…
