Question
The flux linkage () and current () relation for an electromagnetic system is . When A and (air-gap length) cm, the magnitude of mechanical force on the moving part, in N, is ________.
Correct answer
186 to 190
Solution
The mechanical force in an electromagnetic system can be derived from the co-energy .
Given: Step 1: Calculate the co-energy .
Step 2: Calculate the magnitude of the mechanical force .
Step 3: Substitute the given values ( A, cm m).
NThe magnitude of the mechanical force is approximately 188.56 N, which falls within the range [186.0, 190.0].
