2-D and 3-D Analytical Calculation of the Magnetic Field and Levitation Force Between Two Halbach Permanent Magnet Arrays

IEEE transactions on magnetics, 2021
As we know, the analytical calculation of magnetic field and magnetic force has important guiding significance for the optimal design of the size and structure of a magnet.

Levitation Force Characteristics of High-Temperature Superconducting Bulks in a High Magnetic Field

IEEE transactions on applied superconductivity, 2020
The levitation force of high temperature superconducting (HTS) bulks can be enhanced by raising the strength of the external magnetic field. As to the field of HTS magnetic levitation (maglev), many researchers have also obtained this conclusion by ...

Levitation Force Improvement by Effective Magnetic Interaction in Two Magnetic Levitation Systems With HTS Coil and Bulks

IEEE transactions on applied superconductivity, 2020
In this article, we studied a magnetic levitation system which was composed of a high-temperature superconducting (HTS) coil, HTS bulks, and a ferromagnetic material (rail). We set two magnetic levitation systems in one ferromagnetic rail.

Measurement of Holding Force and Transportation Force Acting on Tabular Object in Near-Field Acoustic Levitation

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2022
The holding force acting on a levitated object during near-field acoustic levitation has not been statically and directly measured so far. In this study, it was considered to realize such a measurement when a levitated object has a large displacement ...

Axial Vibration Characteristic of Levitation Force for Radial-Type Superconducting Magnetic Bearing

IEEE transactions on applied superconductivity, 2020
Dynamic levitation behavior is crucial to the stable operation of superconducting magnetic bearing (SMB). In this article, we mainly focus on the axial vibration characteristic of levitation force for the radial-type SMB.

Magnetic Levitation Forces—Circular Coils

Canadian Journal of Physics, 1973
Magnetic vector potential is used to derive lift and drag forces for arbitrary coils moving parallel to infinite conducting slabs. It is shown that at high speed the ratio of magnetic lift-to-drag forces for a circular coil whose diameter is small in comparison with its height above the conducting slab becomes 0.6763(hλ)1/2, where λ = μσv.

Spark plasma sintering of bulk MgB2 and levitation force measurements

Superconductors Science and Technology, 2020
We present preliminary results suggesting that MgB2 is a superconductor that could be used in Maglev vehicles. For this purpose, we compare the levitation capability of MgB2 samples to those of YBCO bulks.

Optically levitated stylus for scanning force microscopy

Conference on Lasers and Electro-Optics Europe, 1996
A single-beam optical gradient trap could potentially be used to hold a stylus for scanning force microscopy1. An optically trapped particle can be modelled as a harmonic oscillator and can thus be characterised by its spring constant. We have determined the spring constants for particles trapped in both Gaussian and donut beams2, using a novel ...

Dynamic Simulation of the HTS Maglev Vehicle-Bridge Coupled System Based on Levitation Force Experiment

IEEE transactions on applied superconductivity, 2019
In this paper, we built a high-temperature superconducting (HTS) maglev vehicle-bridge coupled system model by Universal Mechanism (UM) software, and analyzed the vertical dynamics.

Vertical–Lateral Coupling Force Relation of the High-Temperature Superconducting Magnetic Levitation System

IEEE transactions on applied superconductivity, 2021
A high-temperature superconducting (HTS) magnetic levitation (maglev), based on YBaCuO bulk superconductors and permanent magnet guideways, shows the potential to be applied in the future rail transportation.
