The boys are Australian migrant children nominated by their schools, and this program appeared on Australian TY sixty years ago. Did you even read the other comments?

@rayfairall4126 you know I'm trolling right?

@@A-a-ron666 No I didn't know. A member of my school was nominated to attend the accompanying lecture series at Sydney University.

@rayfairall4126 oh cool

Gargamel? Good French name.

@burchified”Now if you imagine, that this Smurf had no magnetic history, and I were to hold it so, and strike it with this hammer, it would no longer be able to send me exploding presents?”

This is who they patterned gargamel from. Here's another, did you know bob dillon is the inspiration for butthead?😂

The Earth's magnetism *is* a necessary part. The hammer blows simply disrupt the millions of magnetic domains in the metal in a predictable fashion. Aligning the rod with the Earth's magnetic field, (or another stronger magnet, the Earth's field is pretty weak over these length scales but the value in this trick is making a magnet when you don't already have one) is what causes them to shift, on average, into a magnetic alignment with each other (which makes the rod magnetic in turn), rather than just scattering randomly with each hit. I don't know why the small additional tilt is needed.

@@rolandkerr577perhaps to make the “polls”in the bar completed.

@ Thank you. So if he hit the iron rod near a powerful electromagnet or permanent magnet, it would adopt a strong magnetic field ”memory” than what can be attained without just Earth’s magnetic field?

@@headbanger1428 Yes. Although, you would want it to be a very large magnet, and you'd have to pick a spot relative to that magnet where the field lines across the rod are very straight, or else there would be some losses in the transfer. I think you could also use two, one on each end of the rod, to get around this problem? Again, I'm concerned that I don't understand why the little bit of tilting is necessary, so maybe that would complicate things. It's worth noting that the review papers I've flicked through on the percussive magnetisation seen in this video indicate it is extraordinarily difficult to pull off in general. Whereas the normal modern method of sticking an iron bar into a powerful electromagnetic coil is extremely reproducible.

@ Very kind of you to share your knowledge and explanation once again. I first remember seeing this on the MacGyver TV series lol! I didn't learn this in grade school for some reason. Glad I now know it's called "percussive magnetisation." Very cool! I wonder if the tilt is due to the 26° of Earth's tilt? 🤔

once you wake up, you will see that without religion, science means nothing.

He might have loved you, and prodded you in the chest too.

Sometimes it's better to use the side of the hammer. The rod is probably 3/8ths of an inch, the front of the hammer is an inch, the side provides more surface area to strike that's probably 1.5 to 2 inches in a rectangle. Makes it kind of a like mallet. Sometimes you have to use the side of the hammer, like nailing between joists, or other tight areas. There are many ways to use a claw hammer.

@@GameDevGary Righty-o, when framing and doing literally any carpentry I use my hammer sideways ALOT.

I bet you got beat up for saying akshuallly a lot in school. What a maroon.

If you're going there. Why not question a Claw Hammer for anything besides nails ? Or is the claw to hold your cigarette while hammering rebar 😂 ... and where are their safety glasses 🤣

@ its also an easy way to ash it!

Wrong. This show was an Australian production and both boys would have been Australian. They both have Aussie accents.

​@@MrRlnansel Well, thanks, didn't catch that. But that doesn't really change anything about why it is a bit hilarious.

What was his own nationality or ethnic heritage? Given that he seems to like bringing that subject up.

@@therespectedlex9794 He says he's from "New England" in the full episode.

@@MrRlnansel New England isn't a country.

That’s where I learned it too

@ Awesome! 👍👌

yeah this was like a "holy shit i've needed this tip all my life" moment. i will never forget this, damn. what a great teacher and students too. how the hell did we get to where we are now, we had this. yeesh.

Spanno looks more Italian than German...

It's short for Spanokopita which is actually Greek.

​@@goofballbiscuits3647 isn't nearly everything in modernity from our Greek ancestors?

@@envisionCamusa I was making a food joke 🥲 it's a Greek spinach pastry.

​@@envisionCamusaMost of us haven't got Greek ancestors.

I'm guessing that a static charge might attract through induction. I'm just amazed to find another method outside of electricity to make a magnet.

The compass is magnetic, and the iron bar is, well, made of iron, so no matter if it's magnetized or not, the compass would pull on the iron bar. So to differentiate between a magnet+metal interaction from a magnet+magnet interaction you use repulsion.

@@yonidellarocha9714excellent. Thanks!

I was raised on that show. 😊 👍

born 1970, only place i've herd hocus pocus dominocus except the last song on treasure by cocteau twins

@@atomictraveller never watched buggs bunny?

That's exactly what occurred to me. It would have made the demonstration much more powerful.

The non magnetised bar would have been FOULED by placing it against the magnetic compass pointer.

​@@cheradeninezakalwe. I doubt that. Besides. He held the rod almost evenly with the compass needle. So you can't even say that if it was Repulsing, Or Attracting. And actually looked like it was attracting it.

​@@cheradeninezakalwe. OOOOOOO, Nice one! Knowledge bomb goes boom. My brain juice is everywhere! HIT ME WITH KNOWLEDGE! I really appreciate you sharing that.

@@cheradeninezakalwe. Ahhhh . . . So it would have been turned into a chicken 🐔 ??

I bet Carl Sagan used to watch this guy
