Investigation on the levitation force behaviour of malic acid added bulk MgB2 superconductors
(Elsevier, 2014)
The effects of malic acid addition (from 0 to 15 wt% of the total MgB2) on the levitation force properties of bulk MgB2 have been investigated. All samples were prepared from magnesium powder, amorphous boron powder, malic ...
Comparison of levitation forces of bulk MgB2 superconductors produced by nano boron and carbon-doped nano boron
(Springer, 2014)
MgB2 bulk superconductors were prepared by hot press plus furnace heating method. Two types of boron powders were used, one is amorphous nano boron and the other is C-doped boron. Characteristics of superconductors were ...
The effect of magnetic field distribution and pole array on the vertical levitation force properties of HTS maglev systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2015)
In this paper, the levitation force measurements have been carried out by the magnetic force measurement system under both field-cooling and zero-field-cooling regimes, whereas the magnetic field distribution over the ...
The size effect on the magnetic levitation force of MgB2 bulk superconductors
(Elsevier Sci Ltd, 2016)
In this study, the size effect on the magnetic levitation performance of disk-shaped MgB2 bulk superconductors and permanent magnets was investigated. MgB2 samples with varying diameters of 13 mm, 15 mm and 18 mm, each of ...
Magnetic levitation force and trapped field properties of multiseeded YBCO with triangular arrangement of seeds
(Wiley, 2021)
Although there are studies in literature using different number of seeds with different arrangements, especially line and rectangular, it is seen that there is no detailed study handling the levitation force together with ...
Improvement in levitation force performance of bulk MgB2 superconductors through coronene powder adding
(Elsevier Science Sa, 2017)
The effect of coronene (C24H12) addition on the levitation force properties of MgB2 superconductor has been investigated for the first time in this study. the polycrystalline disk-shaped MgB2 + y wt % C24H12 samples (y = ...
Lateral force measurements for (Gd123)(1-x) :(Gd211) (x) superconductors at different temperatures

Enhanced magnetic levitation and guidance force in MgB2 bulks by synthetic engine oil immersion
(Springer, 2019)
We have used Synthetic engine oil' as a rich easily accessible carbon source and investigated the effect of engine oil on the microstructure, critical current density (J(c)), vertical levitation force (F-z) and guidance ...
An analysis on the relation between the seed distance and vertical levitation force for the multi-seeded YBCO using the modified advanced frozen image (MAFI) and experimental methods
(Elsevier Science Sa, 2019)
The higher magnetic levitation force and related stiffness values are very important for Maglev and magnetic bearing applications. Also, larger superconducting surface area is needed for continuous and larger magnetic ...
Magnetic properties of the welded joined TSMG Y123+x wt% Y211 (x=20 and 30) bulk superconductors
(Elsevier, 2019)
Although the welding techniques have been used to join for bulk YBCO superconductors with a sintered superconductor, similar technique as a Ag2O added bulk YBCO superconductor fabricated by melt-powder-melt-growth process ...
