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

Click For Summary
SUMMARY

The discussion centers on the electromagnetic induction effects when a magnet is passed through a copper coil with its poles rotated 90 degrees. It concludes that in a perfect coil, no voltage or current would be induced due to the symmetry of the setup. However, in practical scenarios with real coils and magnets, some minimal induction occurs, although it is not significant. This highlights the importance of coil imperfections in real-world applications.

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.
