1. "Consequent pole bipolar field magnet with two coils on the cores. 2. "A separately excited DC generator with bipolar field magnets . 3. In a magneto the field magnets are permanently magnetized. 4. These authors used the criterion to determine the lower critical dimension of random field magnets . 5. Research in the high field magnets of the EMFL leads to new insights in material properties. 6. "Modern dynamo with four consequent pole field magnets . 7. The smaller generator can be either a magneto with permanent field magnets or another self-excited generator ." 8. The former has its field magnets F F magnetized by means of a small current flowing around a shunt circuit. 9. Bipolar generators were universal prior to 1890 but in the years following it was replaced by the multipolar field magnets . 10. "A self-excited shunt-wound DC generator is shown on the left, and a magneto DC generator with permanent field magnets is shown on the right.
