The Difference Between Paramagnetism and Ferromagnetism

The attraction of a paramagnetic substance to a strong magnetic field is demonstrated. This is contrasted with the effect of a magnetic field on a ferromagnetic substance.

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

[Keerthivasan]

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

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

[singharminder]

very well explained with practical examples, thanks

[dayannabriseno]

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

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!

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.

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.

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.

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

[danielpopa]

it helped me understand what the difference is between the two

[rossfriedman]

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

[rossfriedman]

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

[chanakyasinha]

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..

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

[rossfriedman]

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

[Barakat]

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

[MolarFox]

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

[youspinmerightrounds]

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