Paul, question - I have a 415v MEM starter on a saw, how or what do I need to do to the coil (Solenoid) so it would work with 240v, more coils of wire on the coil? or less? and could I measure the resistance in the coil - no sure what that would be? thanks for any help, Paul

[@pidayrocks2235]

@@martinkuliza I beg to differ... just because you've been exposed to really cool science/engineering before doesn't inherently make it any less amazing later... particularly if you've learned more about the underlying concepts in that time frame. I'm an engineer at MIT and I continue to find these videos to be amazing because it demonstrates a complex phenomenon in a simple way.... the more physics you learn, the more you will appreciate that.

[@martinkuliza]

@@pidayrocks2235 oh.. you're an engineer, cool well then you'll understand me on this then..... Yes i agree with what you're saying but meet me half way on this point ok.. even though playing with magnets and their behaviour is always interesting, playing with magnets over and over again gets dull after a while now... i guess we can call that a human condition to me this is somewhat boring at this point in the game because i was doing this stuff from a young age i agree it's interesting for the newcomers and that's fine, it's on the same level as interesting as making a battery out of a few lemons and connecting them up in series to get a volt on your DMM i suppose as we go along we crave more interesting things and more challenging concepts so if we go back to lemons and magnets, it kinda gets dull, you know what i mean but, i'm not discounting or forgetting how amazing it is to begin with, so.. i do understand what you're saying.

[@IlasBosch]

Excellent video. I especially liked the last part where you create your own solenoid switch. I got one addition to the right-hand grip rule: the direction of the magnetic field (where is N and where is S) not only depends on the direction of the current flow. It also depends on the winding direction of the solenoid: are the windings (seen axial wrt the solenoid) wrapped clockwise or counterclockwise. Your rule is correct in the case of CW. If they are wrapped CCW (and same current direction ofcourse) then the N is on the left and the S is on the right.

[@parthmaheshwari3673]

Thanks for the brilliant video! I have a question though. At 8:29 when you push the nail fully into the container and pass current through, how is that generating a pushing force and pushing the nail in the opposite direction when you haven't flipped the terminals either?

[@jamesgarner4127]

He just used this as a crude example of the basic function of a solenoid. I believe the amount of winding and current would be factored in to a manufactured product and the return or open position could be achieved with a spring or additional wiring to reverse direction.

[@calvinrule6635]

I believe it is because the wires magnetic field aligns the nail to the centre of the coil. It looks like it just overshot a little because it didn’t have anything stopping it in the first example

[@lawrencewinter]

Great vid but there's one shocker. Establishing the North end of the solenoid. It's not true to say that the the direction of current flow gives the North side (4:14). The wires can be wrapped clockwise or anticlockwise and this gives two different orientations. Please correct this, it's causing misconceptions. I would have used this clip for teaching but it will create headaches for me.

[@ryanmarshall4741]

Engineering mindset: I'm really interested in @ 8:17 where you have the nail in the homemade coil, in knowing which way the nail will go, depending on the direction of current. So, if running current through a wire induces and magnetic field, and a coil magnifies that magnetic field, and pointing your thumb in the direction of current flow means that your thumb will point towards the North pole of the coil, then, and please confirm that I am understanding this part correctly, it seems that you will turn the nail into its own bar magnet. Now, the question is, which end of the nail is which pole? I think that, per 8:40, it seems like the nail stops perfectly centered in the coil, therefore, I think that the left end of the coil is the North pole, because due to the right hand rule, that's the direction of flow of current, and your thumb points toward the North pole, therefore for the nail, the left end of the nail, it is the South pole, that way the nail stays centered in the coil as if the nail was its own bar magnet and the ends of the nail are opposite the ends of the coil. Did I get this right?!

[@LSmiata]

Great video!....but have question on homemade solenoid. At ~ 7:50 and later. You mention wrapping the stands in the opposite direction...? Maybe I misunderstood and video was too fast, but if you wind opposite, that would reduce the magnetic field potential. In solenoid/coil production, they run strait from the spool and wind back-and-forth along the field axis while always keeping the copper windings untwisted....and never run in the opposite direction (clockwise vs counter clockwise as view from either end of axis) Please advise as I may be misunderstanding your video and others could fall into the same situation. Cheers! Mr. P

[@jovetj]

Winding the opposite direction would have the same effect as reversing the polarity.

[@christianeriksson4733]

I think he ment "forth and back", the turns are still in the same direction but the pitch direction changes. Best regards

Absolutely loved this video, thanks for making it. Donated enough for a coffee in Australia. I have one question - when you say "north pole" of the magnet, what does this actually mean? Are there more electrons bunched up that end of the magnet, or the other way round?

[@EngineeringMindset]

Thank you :D That's an excellent question although it's really a physics question and not engineering so it isn't my expertise but from memory it's to do with the alignment of the atoms and the direction of rotation of the electrons. Sorry I can't fully answer but hopefully that'll put you on the right track.

[@aboutmedicine]

@@EngineeringMindset Thanks mate, that's a great start

[@rh001YT]

from the early times of electromagnetic experimentation, the n. pole of a magnet is that to which the north pole of a compass will point.

[@jovetj]

Magnetic fields have a "flow" to them like an electric current; it's no coincidence that magnetism and electricity are so closely related. Magnetic fields are realized by photons, which also is what all electromagnetic radiation (e.g. light) is. The N/S pole names drive from the magnetic field of the Earth itself. When you hear on the news about the "magnetic pole flip" that might be coming ... it's talking about the Earth's magnetic field literally reversing... so N would become S, and S would become N. One of science's holy grails is finding a _magnetic monopole_ - a magnet with just one pole!
