Magnetic Properties

070 - Magnetic Properties

In this video Paul Andersen explains how all material has magnetic properties. Ferromagnetic material can be permanently magnetized, paramagnetic material will align with magnetic fields, and diamagnetic material will align weakly with magnetic fields. Magnetism is a quantum property that acts at all scale levels

that was more than helpful, thank you so much. a 6 mins video explained to me what my prof. failed to do in three lectures...

The magnetic field inside a toroid is totally contained inside the toroid itself. There is no significant magnetic field in the center of the toroid's hole. Therefore, to measure the magnetic properties of a substance using a toroid, you must place it literally inside the toroid core, and not in the hole!

[garimasharma]

That was really good! Thank you so much!

[syedghauseibrahim]

Your explainations are to the mark. Excellent. Thank you!

[manthasagittarius]

Good, very clear and useful. You make good teaching materials -- teachers will use them.  Thanks!
Happy New Year!

Thank you for the concise explanation. That really cleared this subject up for me.

[varianrizkyalfandi]

not just really simple, but it was greatt explanation

[mawada-juux]

Yea that was very helpful all thanks to you 👍💫

[cbmughda]

It was very useful! thank you so much for sharing!

if the graph can have the B, flux density, H field intensity vectors magnitudes
it would help.

hello,
just to clarify; if I heat a ferroelectric past its Curie temperature. it becomes paramagnetic.
then once it cools down below its Curie temperature, it returns to being ferromagnetic?
or does this vary with different materials?

[nadie-qmrq]

should have found this video before my test

[patricknebe]

Hello, please why didn't you mention anything about Ferrimagnetism and Antiferromagnetism?

[EmNemmo]

Why is magnesium paramagnetic? I thought it was diamagnetic because all of its electrons are paired.

My question is simple we see metals non metals other substances in periodic table where we can see these magnets.
We find magnets naturally in the universe what are those materials are made of are they metals.
How is there Quantum structure that make them magnets

[anishabisht]

So we need a really big magnet to repel our body?

[mr.c.kumar.biswas]

What is this iron repel? Sir please repel camical name

[MatheusSilva-dragon]

Hey, Mr. Andersen, if I induce an electrical field in a diamagnetic material through friction does it get easier to induce magnetic fields parallels to the desired magnetic field? After all, some of the electrons are removed.

[muhammadayyankhan]

why magnetic properties increase as vacancies increases?
