1. Why does increasing the applied voltage end up increasing the motor's speed? Explain the effects of increasing the applied voltage in a step-by-step fashion. 2. Describe the path the current follows through the motor. 3. What causes the armature's magnetic polarity? 4. If you place a compass needle between two fixed bar magnets and give it a spin, it eventually comes to rest. So why does the DC motor's armature keep spinning
