Abstract
This paper presents the numerical modeling results of the temperature for a YBCO-type high-temperature superconducting (HTS) winding of an electromagnet that generates a magnetic field with a maximum magnetic flux density of 5 T. The electromagnet is made in a Helmholtz configuration, with circular double pancake-type coils. Inside the central area of the electromagnet is placed a measuring cell with the sample exposed to the magnetic field, which has a variable temperature in the range of 4.2 to 300 K. The change in the temperature of the HTS winding due to the radiative thermal heat absorbed from the cell, is studied as a function of the temperature of the measuring cell, which can vary between 4.2 K and 300 K. The modeling results shows a maximum value of 0.334 W which give rise of the temperature of the HTS coils to 5 K.
