Measurement of the spatio-temporal distribution of harmonic and transient eddy currents in a liquid metal
Jan Forbriger, Vladimir Galindo, Gunter Gerbeth +1
Harmonic and transient eddy currents in a liquid metal positioned above an excitation coil are determined by measuring the voltage drop in a simple potential probe. The resulting s…
Coexisting stochastic and coherence resonance in a mean-field dynamo model for Earth's magnetic field reversals
M. Fischer, F. Stefani, G. Gerbeth
Using a spherical symmetric mean field alpha^2-dynamo model for Earth's magnetic field reversals, we show the coexistence of the noise-induced phenomena coherence resonance and sto…
The integral equation approach to kinematic dynamo theory and its application to dynamo experiments in cylindrical geometry
Mingtian Xu, Frank Stefani, Gunter Gerbeth
The conventional magnetic induction equation that governs hydromagnetic dynamo action is transformed into an equivalent integral equation system. An advantage of this approach is t…
Reversals in nature and the nature of reversals
Frank Stefani, Mingtian Xu, Luca Sorriso-Valvo +2
The asymmetric shape of reversals of the Earth's magnetic field indicates a possible connection with relaxation oscillations as they were early discussed by van der Pol. A simple m…
Experiments on the magnetorotational instability in helical magnetic fields
Frank Stefani, Thomas Gundrum, Gunter Gerbeth +3
The magnetorotational instability (MRI) plays a key role in the formation of stars and black holes, by enabling outward angular momentum transport in accretion disks. The use of co…
