In the shaded pole squirrel cage induction motor the flux in the shaded part always
- A. Leads the flux in the un-shaded pole segment
- B. lags the flux in the un-shaded pole segment
- C. is in out of phase with the flux in the un-shaded pole segment
- D. is in phase with the flux in the un-shaded pole segment
Answer: B. lags the flux in the un-shaded pole segment
Explanation: By Lenz's law, induced currents in the shading coil oppose any change in flux; hence flux in the shaded portion lags behind the flux in the unshaded segment, producing a shifting magnetic field.
