Amazing video, it made me understand the way magnets work in a microscopic level a little bit better. Thanks for uploading.

this was super helpful for my 7th grade project on magnetism and what makes ferromagnetism, diamagnetism, and paramagnetism different from each other :)

I enjoyed watching this and it's helpful! Thank you!

very well explained with practical examples, thanks

It is a nice practical description of the magnetic behavior. Thank you for the effort

Although I basically agree with your comment, you imply that an odd number of electrons is necessary for paramagnetism. Ni2+ compounds are paramagnetic and so is molecular oxygen. Both have unpaired electrons. In fact liquid oxygen can be observed to be attracted to a magnetic field.

The manganese in this video is in the form of MnCl2 dissolved in water. The electron spins on nearby Mn+2 ions do not interact strongly with each other and therefore the spins of adjacent ions are randomly aligned. The same is true about solid manganese metal. Both substances are paramagnetic. Iron metal is different. The spins on the nearby iron atoms in the metal do interact strongly. They interact in such a way that they spin parallel to one another.

Thank you for the simple explanation

Paramagnetism is found in elements with an odd number of electrons.Applied magnetic fields cause the electron spins to align.The spins create their own magnetic field;the collectively field of the aligned electrons is called paramagnetism.Diamagnetism is found in all elements but only noticeable in those with an even number of electrons. It's caused by the externally applied fields changing the electron speed. Ferromagnetism is a quantum behaviour causing strong interaction & alignment of spins.

Thank you for the great video. I'm taking grade 12 chem online and reading chemistry explanations from a textbook can be very difficult. This video really helped me understand the concept. Thanks!

Thanks for the demo!

very helpful revision thank you!

Thank you great demo ..

Insightful

very nice, thank you very much.

it helped me understand what the difference is between the two

Thanks a lot for the Information

thx , very useful video .

nice, i was looking for a German explanation but this worked perfectly thank you =)

Why don't the electron spins in the paramagnetic materials agree to line up as well as the spins in the ferromagnetic ones?

thnnk u sir for ur explaination

I really wanna understand the relationship between this and larrmor frequency. It seems to me like larmor precession will do a neat job of explaining why some materials are ferromagnetic and some paramagnetic, and explaining magnetic hysteresis and saturation, but i cant find a video/essay putting it together. I think im doomed to trying to decipher some physics lecture notes XD

So a ferromagnet is the something is a natural or permanent magnet and a paramedic substance is something that's an induced temporary magnet?

Doesn't permanent magnet looses energy continuously as electrons have same spin, i mean like a in a transformer... If one coil has clockwise current, the other shorted concentric coil will have counter clockwise spin... Dont the electrons feel resistance at molecular level..

thumps up If I can ask you why manganese is paramagnetic and iron is ferromagnetic ?

I know it's been five years since this was made, but to confirm - does north-seeking mean the same as North Pole? (IE - field lines would be drawn with arrows retreating from that pole in either side?) (and the same for south-seeking / South Pole) Proper good vid, makes me all nostalgic watching it

The north pole of a magnet seeks the Earth's magnetic North Pole. According to Physics.org, the Earth acts like a magnet with the south pole of the magnet in the north and the north pole of the magnet in the south.

Charles Marzzacco Ah right, so that only works when comparing to earth's magnetic north/south. Cheers for the response, never heard that term used before

Thanks 😄

Hi Charles, that's a typo alright! It should read unpaired electrons

Are you saying that magnetic elements are never electrically satisfied? Like their electron shells are never completely full?

Or it's just easier to line up the spins?

nice movie wait! its not a movie
