PH EM MF DEMO 70011A V0513 3D Magnetic Field Demonstrations Bar and Horseshoe Magnets

A striking visualisation showing the 3D nature of the magnetic field lines that surround a cylindrical bar magnet and a horseshoe magnet.

[@AethericEchoes]

That's a clever little device. Much more revealing than the standard 2D magnetic viewing film.

[@Albylion]

THIS. This is what I've been yearning to see as I try to study electricity from the election up. This video helps fill the gaps in my knowledge left from the same 2D illustrations in every book and web post on the matter. Thank you for this!

[@Greg_Chase]

This is the very best visual display of magnet field effects I have seen. Just perfect, it is a well-thought-out display in 3 dimensions. I wish that more people in our field would come to terms with, and ponder on: 1) the exact same result will occur in space, outside the atmosphere 2) the invisible influence of the magnet on the polarization of the small compass needles actually does require an 'essence' to communicate the electron spins inside the magnet to the electron spins inside the small compass needles The source of magnetic fields from a permanent magnet is the alignment of electron spins in the ferrous material (iron, or nickel, or cobalt). Space - also called "the Vacuum" in physics parlance - is a dielectric that can be polarized. Since polarization - of electron spins in the small compass needles - requires dipoles, I wish that more people in our field would pursue a line of reasoning that the Vacuum has a dipolar essence. "But we can't see anything, and we can't measure anything" - that doesn't mean it's not there. See "Vacuum Permittivity" and "Vacuum Permeability" if you're interested. Thank you for the excellent demonstrations!

[@dredrotten]

That was a cool demo,thanks for taking the time and effort to do that, its appreciated.

[@jeffb2002]

Thank you. The horseshoe magnet was not at all what I expected. Darn it!

[@josebeijing]

thanks very much sir, the best video i have seen about magnetism.

[@jamesyee1456]

Engineering students, you just don't know how good you have it nowadays

[@sn5953]

One word: awesome! I have seen videos that try to demonstrate the magnetic field lines in 3D using iron filings floating in some sort of a low viscosity liquid. Those illustrations aren't as effective as this one. Many thanks for this illustration.

3D is better than 2D. 👏

[@sanchitjain89]

Beautiful

[@sujatabhowmick9159]

wonderful video..

[@ubergeraldine]

Very nice!

[@tshisreletsogaoganediwe330]

thanks for the video man

[@DavesCave]

love tue perspex with compass needles. would like to see thr needles coloured north and south but thats not a biggie. what happens when you join to horseshoe magnets together?

[@sporg]

A wonderful exhibit. But..... from the point of view of a good video... wouldn't it be better at the start to have the compass needles randomly pointing (by giving the model a good shake at first), so that the insertion of the bar magnet made them snap into place?

[@gristlevonraben]

Very cool

[@yasmenkndel2635]

Amazing

[@AaronicHighPriest]

Good idea

[@iskandarsyah9624]

Interesting, I wonder how It would look like if there were more degrees of freedom for the individual compass needle.

[@drprashantpervatikar513]

What occupies the space between the field lines?

[@rubens.4116]

This another cool tool to make the fields become visible. But I prefer the one with iron shavings in a flat clear water filled flask.

[@michaelcowell4156]

I would like to purchase this demonstration kit for my physics classroom. Can anyone provide a link to where this product can be purchased? Thank you!

[@vedamurthyg685]

Hai everyone who is seeing this video. This is very useful t o 10th cbse students as this experiment is in their textbook.So dont miss it.

[@Thanos-hp1mw]

Cool.

[@drprashantpervatikar513]

How do we know the field lines exit through the N pole and enter through the South Pole? Can it be demonstrated?

[@cdignazio4772]

How are you spinning the magnetic field demonstrator? My students are perplexed.

[@kevinritter6448]

+catherine dignazio The table top it is sitting on turns.

[@cdignazio4772]

Thank you;)

[@northernnomad5116]

[@David-yy7lb]

It would be really cool to see the magnetic field through a special camera just like you can see infrared 👍🏾👍🏾I'm just surprised no one has developed a camera or something that can see a magnetic field without using iron filings or ferro fluid

[@muratkul7377]

Would be much better if N and S poles were painted to different colours.

[@29gopikrishnap2]

basically arent compasses themselves magnets huh ? so why arent each of them having an effect on their adjacent compasses

[@avijitdey992]

I guess their mutual effects are negligible as their mag field is very less. But horseshoe magnet has a strong mag field

[@getsmarthypnosis6850]

Now some of my friends and I argue about N and S poles. When you label your magnet "North" pole, are you saying that is the end that attracts the end of the compass needle that points to our north pole on the earth?

[@SirTravelMuffin]

When the north and south poles were named, they were named after the direction that they point in, north points north and south points south. However, just like charges, opposites attract. Negative attracts positive and so South attracts North. While the compass needle points north it is actually being attracted to a 'South' pole.

[@maazkhan6947]

I cant ur point can u explain it further? I am student10th pakistani

[@solarfluxman8810]

Travel Muffin is correct. The end of a magnet which is marked north, is north seeking. If you were to make a compass out of it, the north end would point to the Earth's geomagnetic north pole located in northern Canada, but that pole on the Earth is actually a magnetic south pole. Hope that helped.

just to clarify. I mean to make a closed loop like a donut
