摘要：
We have designed, built and tested three magnetizers that enable fast and inexpensive magnetization of YBCO bulks with the FC method. The first device consists of a permanent magnetic circuit with moveable magnetic poles. The other one is a hybrid magnetizer where we applied permanent magnets and properly designed coils with dc current excitation. The third version is a magnetizer just with an excitation coil without cooling. In this case we have measured 2 Tesla at 2650 W electrical power in 18.4 mm air gap. These solutions are of low cost.
