Abstract

A hybrid trapped field magnet lens (HTFML) can reliably generate a concentrated magnetic field, B c, in the centre of the magnetic lens higher than the trapped field of the trapped field magnet (TFM) and the applied magnetic field, B app, even after the external magnetizing field decreased to zero. In this paper, the performance of HTFMLs consisting of EuBaCuO bulk TFM with various heights and a GdBaCuO bulk magnetic lens was investigated at 77 K using liquid nitrogen. A concentrated magnetic field of B c = 0.80 T was achieved at the centre of the HTFML for the tallest TFM after removing an applied magnetic field of B app = 0.50 T. The influence of the height of the outer TFM cylinder on the final concentrated field was studied experimentally and discussed using numerical simulation.
