🔍 Key Concepts

• DC shunt motor field polarity and how magnetic fields are detected • Effect of current direction on magnetic polarity (N/S poles) in field coils • Which test methods can actually show you a north/south pole reversal rather than just continuity

💭 Think About

• Which option would let you see or detect a change in magnetic polarity if the current direction in a field coil were reversed? • Which methods only tell you that magnetic flux exists, versus telling you which way that flux is oriented? • Think about which instrument or tool is commonly used to detect magnetic direction rather than just the presence of metal or voltage.

✅ Before You Answer

• Identify which option directly indicates north/south magnetic pole direction at each field coil • Eliminate any choices that only test mechanical attraction or electrical continuity without indicating polarity • Ask: which method would clearly change its indication if the field leads were swapped (reversed)? That’s the one that can find a reversed shunt field coil.
