MagTense: a micromagnetic framework using the analytical demagnetization tensor
R. Bjørk, E. B. Poulsen, K. K. Nielsen +1
We present the open source micromagnetic framework, MagTense, which utilizes a novel discretization approach of rectangular cuboid or tetrahedron geometry "tiles" to analytically c…
The magnetic field from a homogeneously magnetized cylindrical tile
K. K. Nielsen, R. Bjørk
The magnetic field of a homogeneously magnetized cylindrical tile geometry, i.e. an angular section of a finite hollow cylinder, is found. The field is expressed as the product bet…
The stray- and demagnetizing field from a homogeneously magnetized tetrahedron
Kaspar K. Nielsen, Andrea R. Insinga, Rasmus Bjørk
The stray- and demagnetization tensor field for a homogeneously magnetized tetrahedron is found analytically. The tetrahedron is a special case of four triangular faces with consta…
The demagnetization factor for randomly packed spheroidal particles
R. Bjørk, Z. Zhou
We investigate if the demagnetization factor for a randomly packed powder of magnetic spheroidal particles depend on the shape of the spheroidal particles and what the internal var…
A topology optimized switchable permanent magnet system
R. Bjørk, A. R. Insinga
The design of a magnetic field source that can switch from a high field to a low field configuration by rotation by of a set of iron pieces is investigated using topolog…
The maximum theoretical performance of unconcentrated solar photovoltaic and thermoelectric generator systems
Rasmus Bjørk, Kaspar K. Nielsen
The maximum efficiency for photovoltaic (PV) and thermoelectric generator (TEG) systems without concentration is investigated. Both a combined system where the TEG is mounted direc…
