Ah, but it does deflect! It quivers back and forth in sync with the polarity of the AC, but except for very low frequencies (e.g. < 1 Hz) you won't be able to see the quivering. I saw it in high school electronics using a hand cranked alter...

This helps produce an approximately radially symmetric magnetic field. The field lines are like radii of a circle spaced at equal angles. This means the field strength is constant for different coil angles and the scale can be kept linear (...
