| As shown in the illustration of a DC machine which is configured as a generator, what is the polarity of the interpoles as compared to the main field poles? EL-0052 |
| A) in the direction of rotation, the following interpole should have the same polarity as the preceding main pole |
| B) in the direction of rotation, the preceding interpole should have the same polarity as the following main pole |
| C) the polarities of the interpoles 180 degrees opposite one another should be the same, the actual polarities compared to that of the main poles does not matter |
| D) in the direction of rotation, the preceding interpole should have the opposite polarity as the following main pole |
