Magnet through a copper coil - What if poles rotated 90 degress

Main Question or Discussion Point

I was wondering what voltage or current, if any, would be produced if the basic magnet through a copper coil experiment had the poles rotated 90 degress so north and south faced the top/bottom of the coil rather than the entry/exit points?

The attached image has a basic illustration of this.

Thanks

In the limit of a perfect coil, there should be no induction due to the symmetry of the problem. A real coil is not perfect (and the same is true for the magnet and its motion), so you will get some induction, but not much.
