He means LINES OF FLUX. Its just a term used to describe or graph the magnetic field. The lines aren't actual material but for obvious purposes are used to show the direction of the force. Neat assembly!!!
Awesome device!!! I was trying to come up with way to see the invisible magnetic field then I ran into this.... Very nice! You should patent this and sell it, if you have not done so already.
A magnetic field does not have _any_ lines of force. It is just a field (nicely shown here). The school children who think the actual field occurs in lines, because of such lax language, are legion. In class, kids are confused (barely knowing it), so they adopt the same language (usually thoughtlessly) that their all-knowing teacher uses. It's a great example of how to teach kids to mimic rather than think. Then when some of those kids become teachers they teach more kids not to think.
I'd like to see something like this built with magnetic field viewer paper instead of the arrows. E.g. the green paper with magnetic particles suspended in oil.
This is a really nice piece of kit but i think you should consider re-naming it. The term lines of force is misleading as the force is perpendicular to the field lines at every point.
it would be great to place lighty magnetic particles in syrup and be able to make the flow from a north source of particles to rest at a south source in slow motion.

Magnetic force, Jack! Nature's force!
Wow, great presentation. Seeing the magnetic field in 3D is very cool.
Cool... it makes cleas magnetic fields shapes. Awesome!!!
if you make each of the needles a magnet in its own right and mark it with North and south colors it will make it even clearer,great model.

beautiful realy, felicitation
ThankReally, Reall cool device.
Very informative
Can I use a small clip for my TH-cam channel?
This is awesome.
Awesome!
this is really excellent

nice toy dude .... ;)
Спасибо классно.
beautiful
great presentation
very good presentation
Да это магия!!
Cool
nice small magnetic compasses
so nice real practical
wowww
Are these devices legal?!
I don't wanna get arrested for messing around dangerous equipments that could explode or something.
hmmmmm nice
nice school stuff
why not use sandwiches of ferro fluid instead of compasses.
@nightsurfer1 you can buy at sci-supply!
should have put on a rotating surface but cool demonstration
get a rodin coil in it man!
Thanks
nice
Y U NO USE IRON FILLINGS?
FREE ENERGY PEOPLE ITS TIME TO WAKE UP!. THE SUN IS SHINING!
its a pointless thing to buy but you can make images of the fields of ya want
ого!
shut up and take my money
o_0 ?
