    Wonderful video! It's very informative(duh!). Thankyou so much❤. I just have a small doubt(although I am not sure if it has already been discussed in the video) - if the Curie temperature of Gd is 20 degree celsius, wouldn't it be just a paramagnet at room temperature? Is our classification of magnets into dia, para or ferro based on room temperature? 🤔

    Magnetism is dipolar only. How does a globe Earth have two external opposing poles while containing a neutral core? A sphere should have a field that is either entirely internal or a neutral external equator to converge opposing external poles. Why is Earth described as tripolar while we know there is no such thing as a magnetic tripole? I say it's because the Earth isn't actually a globe while we have been lied to and deceived along the way.

    Exellent video. I just have one question. Lets say i have a thin bar of 100.000 tons of gadolinium at 19,999999°C .Above this bar i have a magnet(BIG one) who then lifts the bar. Now i use my small candle in the bar just to raise its temperature to 20°C so it falls. Now i wait a little so the bar comes back to 19,9999 and alll the 100.000tons goes back up. Obviouly something is missing since i cant lift 100.000 tons at will just with a small flame. My question is : what is missing?

    For anyone still curious, the reason that the magnetic moments align in the domains is due to the Pauli exclusion principle. Energetically, it is more beneficent for the magnetic moments to align in the same direction, than it is to align in the opposite direction. By the exclusion principle, magnetic moments that are aligned in the opposite direction can be closer to each other, but this results in higher Coulomb energy. For the less Coulomb energy, the magnetic moments need to align the same way to be further away.
    Edit: also, it's not the domains, that align, but the boundary of the domains expand. Domains where the magnetic moment is in the direction of the external magnetic field expand, while other domains shrink

    What about the element Neodymium? Wouldn't that fall under the ferromagnetic category? When you purchase Neodymium magnets, they are insanely strong.

    • @dodokoi036
      @dodokoi036 Рік тому

      I searched a little about it and the element Neodymium has a curie temperature of -240°C so they behave as paramagnetic at room temperature... Also the Neodymium magnets are made of an alloy of iron boron and Neodymium
