Conditions required for magnetic confinement of antihydrogen atoms are briefly described. Then, several ideas of antihydrogen confinement in minimum-B fields are introduced with some comments. Two methods for extracting antihydroten atoms from their synthesized region are also described. Paul trap with a superconducting wall cavity has the potential to trap antihydrogen atoms in a space with no steady magnetic field.
