Our neighbor had someone come in and pour concrete from his foundation to the property line. The ends of all the downspouts on that side are now buried in concrete.
Referring to Dave's post about Altzheimers and the extension cord: I KNOW this is wrong, but somehow I feel that there is not as much voltage drop if I don't uncoil the cord all the way.
The magnetic field generated by 150 ft of cord in coil drawing 18 amps scared the shit outta me..
I did theater work many years ago and one evening on a raod show the main lighting guy got in a hurry and coiled up about 200 ft of wire feeding the light board... he also had left a light mount bracket in the center.. when he powered up the board the damn bracket stood on end!!! Granted this was about 100 amps and it was a tight coil but.....
And the V drop has nothing to do with the coil.. it's all based on resitance.. with that crappy 18/2 wire and the crappy connection in the plug/sockets, YIKES!
If you were describing a coil of two or three wire cord, then....
Idon't understand why the two magnetic fields from the outgoing and return currents didn't cancel each other nearly completely.
Only way I can see something like this happening is if there was a short to ground at the far end so there was no return current. And even then, what was the ac magnetic field working against anyway?
I'm not saying you didn't see what you saw, Leo, but I doubt that it was caused by a magnetic field.
Feeds to portable dimmer banks are typically made with single conductor cables with 250A (rated) Camlock connectors, usually 5 for three phase, neutral and ground.

(clip) ^^^^^^^^^^^^^^^ You can say I didn't see what I saw, "cause I'm not the one who "saw" it. I agree that a coiled up electrical cord would have almost zero inductance, and that the current in the two halves of the circuit would cancel.
My remark about thinking that the coiled-up part of the cord doesn't count was meant to be facetious. Let me give you another example of that kind of thinking. I live in an area which frequently has smoggy days. But I don't worry about it, because the smog always seems to be off in the distance.
Reminds me of a pool I had to repair and they had poured the deck a few days earlier. They didn't put the lid rings over the skimmer or the auto fill and just filled them up with concrete. They did a great job troweling and cool decking around the test plug sticking out above the concrete for the skimmer. It must have been very embarrassing to jack hammer a brand new deck and replace them. Nothing like having a qualified licensed contractor on your job.

I recall reading in a similar thread years ago, of the property management office, which took the collection of standard weights, and drilled a hole in each to rivet a property tag too. then wondered why they were not accepted by the ordering department.
Or the stories of the people who have their septic tank needing cleaning, and then discover that the opening is somewhere under the slab of the extension to the house.
I think I have just read a case for extreme late term abortion. As Bill Cosby said about his dad, "I brought you into this world, I can take you back out".
This is not the curiosity of an innocent child. A 14yo should know better. MUCH better. I suspect if the father was more strict raising his son, and had his son spend more time with him in the shop learning how to work with the tools, then this never would have happened because, (A) the son would have known and appreciated the value of the fine tool and would have had a stake in its utility; (B) the son would have understood how dangerous a loaded press can be; (C) the son would not have disrespected his father with such delinquent behavior; and (D) the son would have known that his father would blister his backside if he even contemplated such a stupid stunt.
Nope. But if I were the father, that boy would have been grounded at least until he had worked-off the purchase price of a replacement level, if not longer.
