<p>PROBLEM TO BE SOLVED: To form a coil which precisely generates a high magnetic field in a set direction, by connecting some of a plurality of electric circuits in series and then connecting them with an external circuit, or connecting the circuits with the external circuit without connecting them in series. SOLUTION: Terminals A9 and B0 for independent connection are connected by using connection wirings (A9-B0) between terminals for independent connection. Scroll coils Al-A8 and scroll coils B1-B8 are connected in series. A terminal A0 for independent connection and a terminal A0' for series connection are connected by using connection wirings (A0-A0') between terminals for independent-series connection. A terminal B9 for independent connection and a terminal B9' for series connection are connected by using connection wirings (B9-B9') between terminals for independent-series connection. When power is supplied between the terminals A0' and B9' for series connection, the scroll coils A1-A8 and B1-B8 are connected in series, and power is supplied. Thereby a small-sized coil which generates a large magnetic field in a set direction with high precision is obtained.</p> |
