				| 1. | Two sinusoidally distributed rotating fields are created by the startor and rotor of a cylindrical magnetic structure. Two fields having same number of poles are rotating in the same direction at the same speed. The interaction of these fields will produce a torque proportional to the sine of the angle between | 
| A. | either of the fields and the resultant field and acts in a direction to reduce this angle. | 
| B. | either of the fields and the resultant field and acts in a direction to increase this angle. | 
| C. | the rotor field (but not the startor field) and the resultant field and acts in a direction to reduce this angle. | 
| D. | the rotor field (but not the startor field) and the resultant field and acts in a direction to increase this angle. | 
| Answer» B. either of the fields and the resultant field and acts in a direction to increase this angle. | |
