Fun fact: Saturns rings contains vast amounts of ice which is diamagnetic... Hence it resides in the place of lowest magnetic field away from poles i.e. around the equator!!
Not as awesome as I'd like. Why does he not make his "spin up" and "spin down" arrows look more like *arrows* instead of, I don't know, sevens or laguz runes? Is that how the kids are writing them these days?
Iain Mackenzie...Looks as if you need to start “learning” as opposed to teaching....I just hope you now know the difference, because that is what is wrong with establishment education....it is not education! It is just teaching....As you just proved!
@@1SpudderR that is very harsh Robert and unnecessarily negative. Education starts when we say "I don't know; I want to learn". To criticise others (including someone willing to ask questions, acknowledge their learning gaps and opportunities) inhibits our culture of real learning. Hence, in my view, contributiing to the dulled attitude towards education in mainstream. Your comments only exacerbate that negative attitude towards real learning. A good teacher is a good learner and models his passion for learning to his students
Iain Mackenzie Hmm....You said it I did not? I only commented on what was my impression of Education in relation to your physical confinement of what teaching Physics is about, after 30 years of missing out on an enormous concept. And since I have been an advocate for the majesty of magnetism since I was three or four, I was amazed at the limits a “Physics teacher put upon himself?” Happily I Observed and responded to the need of Free Thinking out and over of the rut of just teaching, and greedily Seeking broader wisdoms. Perhaps that is your next teaching the learning of “Conscious Phase Perception Of Awareness.” After all conquering Perception is the gateway to conveying Perception. Regards
This is one of the most interesting videos I've ever seen! Not only the demonstrations, but the simple easy to understand explanation. I've been fascinated with magnets all my life, but only as it relates to the interaction with electric currents. I've always liked playing with motors and generators.I hate to say it, but, I'm going to get myself some neodymium magnets, and try this at home.
One of the most clean and simple explanations in youtube. I don't know why some people disliked it. However, I haven't seen any video which got 1k likes without getting dislike.
This was the only source that could really explain paramagnetism/diamagnetism on a level that I need..... Sometimes, I am actually glad that RU-vid exists....
Love seeing science that goes against expectations. Never in a million years would I have guessed water would react to a magnetic field in any way. At least not pure water, uncontaminated by anything.
Wow As a chemistry student who needs to understand magnetism (for VB theory etc, whatever), I've always struggled with physics But this is perfectly simplified, just as much as I need
God, I wasn’t understanding a bit of this subject because my books only had like 2-3 sentences of random physical words to make it hard to describe this basic thing! I’m so glad I found this video!! Its amazing!!!
THANK YOU SO MUCH! my teacher told me not to worry about this topic, but I wanted to learn them because they might appear in the test & they are interesting. this is the best source I have found yet!
ChickenCommander blue chicken commander? Lol jokes Bismuth and other materials could theoretically be used as electromagnetic reflectors in the presence of an enhanced electromagnetic field to provide lift
Excellent, I’ve always wondered about that. Most people have never heard of anything but ferromagnetism and paramagnetism is and interesting effect to display. At work when I am unsure of whether a piece of stock metal is a lower grade of stainless steel or aluminum I’ll take the magnet off of my name tag and slide it down the metal holding it at about a 45 degree angle. If it sticks to the metal it’s low grade stainless, if it slides down the metal like it’s gliding through molasses then it’s aluminum. The magnetic field in motion going down the inclined metal stirs up magnetic eddy currents at right angles to the magnet and slows it’s decent.
Easily one of my favorite videos on RU-vid. Electro-Magnetism is magic of the universe, just like gravity. The fact I can have influence over an object without touching it is amazing. I might end up going to school just to study this stuff further
***** I know oxygen has the configuration of 1s2 2s2 2px2 2py1 2pz1. But for oxygen molecule which is O2, aren't these two unpaired electrons paired by covalent bonding (sigma bonding)?
O2 has two unpaired electrons, which are coupled parallel (the ground state has spin=1) this gives a paramagnetic contribution which overcomes the diamagnetic contribution of the other electron pairs.
This is useful, but potentially dangerous, since some aquatic organisms like to live in appropriate salty environment. Decreasing the salt levels will affect the aquatic ecosystem. Instead we should focus on how to safely break down plastic naturally and quickly. Maybe distorting the plastic structure helps??...
Hey science guy I got a challenge for you show me how to make a water seperater at home caint afford a grand for a store bought one . It separates alkaline water from acidic water. It would be much appreciated if you can do this as simple and as cheap as possible. CAN YOU DO IT?
Xirsi Xussien Hmm...There is no proof of just (Only)the Four elementary or fundamental forces! There are trillions of wavelengths as forces, would you bet a fiver there are not more fundamentals! We should not keep taking concepts as Truths! Concepts are junctions....What type of junction is Fundamental....Perhaps as seems probable the junction contains Roundabouts with Swings.....Now how many fundamental swings and roundabouts are there? And what is Fundamental in the Holistic....Quantum particle Entanglement. Good luck on that one then.
Your Lewis diagram of water showed all paired electrons, so water is therefore diamagnetic. But the Lewis diagram for oxygen (O2) also shows all paired electrons, yet you demonstrated that oxygen is paramagnetic.
+synoptic report Lewis’s theory shows that oxygen molecules are diamagnetic, but in the other hand molecular orbital theory shows different thing. The molecular orbital of oxygen molecules appear as paramagnetic and this is the reason why oxygen molecules have magnetism property.
According to Molecular Orbital Theory, there are two unpaired electrons in the π* that they are in the same direction which increases the magnetic field effect( from the right hand rule). In oxygen molecules.
+synoptic report According to the Lewis diagram or the Valence bond theory, the oxygen will be diamagnetic, but when it comes to Molecular orbital theory, it proves that both the pi anti bonding molecular orbitals of oxygen has unpaired electron, so it becomes paramagnetic.
Although both water and oxygen lewis structure showed no unpaired electron, it doesn't mean that both of them are diamagnetic. By using the MO theory, the oxygen diatom has two unpaired electrons in the antibonding pi-star, and therefore it is a paramagnetic. Unlike water, which has all of its electrons in the bonding orbitals, having no unpaired electrons and thus a diamagnetic.
+synoptic report the lewis diagram in VB theory couldn't explain the experimental result of O2. However, if you use the MO theory, there will be two unpaired electron spins in the 2p pi aniti-bonding orbital. This makes O2 paramagnetic.
Plastic is also diamagnetic. Everything has a diamagnetic contribution, absolutely everything, the question here is how strong is this contribution and how much substance you have. A somewhat empirical aproximation is that the molar diamagnetic susceptibility is proportional to the molar mass of the substance. Chi(dia) = -M/2*10^-6 cm^3/mol Where Chi is the molar diamagnetic susceptibility, and M is the molar mass of the substance (or average molar mass for a mix). To actually get an idea of how strongly diamagnetic an object you're actually holding will be in relation to another one, you can divide this by the molar mass and get the mass susceptibility (which is measured in reciprocal density units of cm^3/g), and then divide it by the density (g/cm^3) to get the adimensional volume susceptibility, this quantity depends on the ammount of substace you're holding.
We had similar film explanations of these phenomena in high school in the 1960s. The difference now is the availability of permanent magnets powerful enough that a little handheld one can be used to give demonstrations like the swivel ones here.
i feel so lucky that you are my Physics teacher. what a smart human being . he is so humble ifnot because of Covid 19, i wouldn't have known you are a "youtuber"
Oh boy, this is where I tell you Jesus is a freq Quincey. The sine wave signature for love and compassion is ever so close to that of bliss. Thus, love and compassion is a precursor for bliss. Mary Magdalene moves the line and waves the sine. Find the frequency, be the freq, share the freq. The creator is the alpha to omega, we communicate in the theta mental state, to be carried to delta is the baptism by fire John the Baptist spoke of and Shadrach, Meshach and Abednego experienced. Only happens in meditation, meditation is medication, exit the church, enter the temple within.
