Yes, but he is using DC, which makes quite a lot of difference. A coil fed with DC, usually with an iron core, is called an electro-magnet. So, it is normal behavior that you can attrack/repel a magnet with a DC coil. Frank Collaris is using AC, which should normally not attrack/repel a magnet, because the north/south poles continiously change places, so it moves back and forth but not move in one direction.....
@dutchguy : Yes, I went to Soest last friday. For me, it was over an hour drive. I live in Goor. I switch trains every day in Zutphen, btw.
IIRC he measured COP by measuring the charge/voltage in the batteries under drain with a 12V bulb, after disconnecting them from the system.





I use them often for Mosfet turn off sharpeners and I just checked, the last circuit I built with them on has them installed back to front, haha the rest are ok, these have different pinout to regular transitors, they confuse me. Another rookie mistake for me.
