I'm not sure that I follow. Do You mean that the forward EMF generated by the collapse of the field is boosted by the magnet going away?

Now here is a new problem: where do I find a simple as possible but still working schema of a circuit like this? This forum is quite big.
I think a thread dedicated to working schema's with comments (but no discussion at all) would be great. If an error is found or info is to be added to a schema the post is edited rather than a new post is added.

This is most surprising to me. I must find a way to check this.
Is this contradicting what boguslaw wrote?

How do I generate and detect this? Do You have a osc-scope-shot?

How do I generate and detect this? Or, where can I read about this?

Again, a thread with working schema's accompanied by comments on how to make it work would be must useful, like a patent-repository (but without its restrictions of course), and no discussions. Not only big apparatus but also small parts to show how a specific concept works (like how all kinds of EMF and all kinds of spikes works).
Unfortunately it seems like the forum-software is compressing attached pictures, but that can maybe be changed?
