Electromagnetic induction and magnet shapes. Help !

Hello. Can someone explain to me how different magnets have a different effect on electromagnetic induction? When you use a normal flat straight magnet the side(polarity) you put it in through a coil, makes the arrow of the Galvanometer move left or right. But if you use a horseshoe magnet it doesn't matter how you flip or rotate it, it always shows the same thing... why?

See the attached file to have an idea for what i am talking about.

Sorry for my English.
