Will this work?

[Ted Ewert]

You may wish to read on a similar concept (i.e. inserting permeable material between two repel magnets or simply inserting permeable material into a magnetic circuit to fill the air gap) here:
Ecklin Stationary Armature Generator

What this guy fails to mention about Ecklins' generator is the amount of drag on the metal plates. Once those plates get into the magnetic field they won't part easily. You would need a fair sized flywheel on the shaft to overcome this counter force, which sort of defeats his premise of not having to move much mass. That premise is also erroneous since it is the Lenz effect in a generator that causes most of the drag and power loss, not the mass of the rotor.
Nevertheless, it would be a fun concept to build and see how much power it could actually produce.

The second magnet has his opposite side near the plate also so drag is very limited really, also sliding a metal on magnet require much less force then to separate both by pulling it away.

Doesn't matter, try it and you'll see what I mean. The more flux that is conducted through the steel, the harder it would be to move out of the field. Put some big neo's in there and good luck trying to rotate the shaft.

I'm sorry to interrupt, but I never mentioned steel in the original post. In fact, I picked bismuth specifically for it's unique properties...

Yes, we understand that, but you do need ferrous metal plates, instead of bismuth ones you originally proposed, to make the device work.

And Ted is quite right - you certainly wouldn't want to use strong neo magnets with a sliding plate design.

Wouldn't be easier in terms of constructing such a device to replace the middle magnet with an electromagnet which polarity would be reversed twice per cycle?

[rickoff]

Certainly it would be easier using an electromagnet at the center, or at each end, but I think the whole purpose of the experiment was to construct a mechanical magnetic reciprocation device.

I would like to revive this thread.
Could someone either confirm or refute my idea, with numbers? Please?
