Abstract
The development of MHD generators is supported in USA by the Energy Research and Development Administration. Several paralell projects like U-25 (a joint work with USSR), CDIF project and AEDC project are currently being carried out.
These projects may be considered as the phase I of the MHD projects of USA. In this paper the design, manufacturing and the test of U-25 bypass superconducting magnet (phase-I) and a conceputual design for the future full scale superconducting magnet (phase-III) are discribed especially among the works done along this line of activities.
