- •
Magnetic characteristics of the Halbach-type PMG at low temperature was investigated.
- •
A four-bulk-superconductor array was set up to simulate an HTS Maglev system.
- •
Temperature–magnetic-field effects on levitation force were tested under ZFC and FC.
- •
Low temperature benefits to the enhancement of PMG magnetic field, while the maximum value happened at 138 K–120 K.
- •
Max. growth rates of 13.4% and 21.8% of levitation force happened under ZFC and FC.
