    This channel is such a hidden gem. There are so many BS videos out there when it comes to magnets. As soon as I saw your DIY Liquid Graphite that Let's you see the Flow behavior.. Turbulent flow, lamaner flow, vortex's, etc. It really was a genius design and I really hope we see a lot more of any future experiments that you end up doing.

    putting to shame most academic labs dealing with magnetism - sure, it's crude and lacks solid theoretical backing but it's exploratory and far beyond what is taught to the public

    You can make very small metalic particles to test with using sodium chloride brine electrolysis. The nacient reaction is removing materials, supposedly one ion reaction at a time. I don't have a microscope to measure particle size but they seep through a 5 micron filter media. You can do this with any metal that reacts with chlorine, but the chlorine is not released, but rather snatched back by the sodium ion it was 'borrowed' from. Leaving the metalic substance free to settle out of the brine electrolyte. You could play with the diamagnetic properties of copper, gold, and other such metals.

    Back to square one...Yes, Very Interesting and now I'm curious, how did you arrange the magnets for the levitating graphite pencil leads?
    Great illustrations and explanations, Thanks!

    • @williamfraser
      @williamfraser  4 месяца назад +6

      Each "V" pair of large magnets has opposite poles facing each other, every second pair is reversed. This creates a strong horizontal field at the bottom of the V. The small magnets helps to strengthen the field but they are not essential.

      @@williamfraser Thanks, sounds logical now you say it. I presume you have glued the magnets in place, so they don't snap together.
      I wonder if there is a difference in performance if the pencil lead is cut to various lengths - a full lead seems to center itself on 4 sets of magnets, and when you pushed it - it seemed to me like it wanted to settle at a particular location as the field lines 'go up and down' in a zig-zag pattern (if I understand right). Also, have you tried with other diameter leads?
      An easy experimental setup, should be fun and interesting to replicate and play around with myself to learn more about the various forms of magnetism.
      Thanks for caring and sharing!

    • @williamfraser
      @williamfraser  4 месяца назад +7

      The steel angle holds the magnets in place, no glue necessary. The alternating polarities give a horizontal field, alternating between pointing left and right. The strength of the field drops off rapidly in the vertical direction. The alternating polarities provide stability along the channel for certain lead lengths. You get good stability for lengths of roughly 1.5-1.8 times the magnet width, and again at 2.5, 3.5 times width etc. Thinner leads levitate higher but the attractive force when floating thin leads on water is weak and tedious to try and demonstrate.

    • @williamfraser
      @williamfraser  4 месяца назад +6

      If lead lengths are less than one magnet width it simply twists sideways, trying to align with the field.

  • @spadeespada9432
    @spadeespada9432 4 месяца назад +3

    The "pencil leads" aren't the same, one is 2b the other b. The five most common grades of hardness in pencil lead: 2B, B, HB, H and 2H and they run in that order, with 2B being the darkest imprint, HB being the middle of the road (used in just about every school in the world) and 2H giving you the lightest imprint of the five grades.
    A European grading system has been developed. The European system combines letters and numbers to represent each grade. This starts from the lightest H grades containing higher clay content, all the way to F, HB, and the darkest B shades.
    The difference in hardness (line weight and color) is a function the chemistry used to get desired hardness or softness, that's the source of the one being attracted vs the other not.

    • @williamfraser
      @williamfraser  4 месяца назад +2

      Yes the softer leads apparently have a higher ratio of graphite to binder. I thought it might levitate higher but could not see any obvious difference. Aside from one other make of lead (Pentel) all others were noticeably more magnetic and did not levitate at all.

      Yes please share when you test it. Since graphite powder is very close to pure graphite (it may contain fractions of a percent of other minerals) we'll be able to compare the behavior of your powder with the one on the video and with pencil leads that are actually a baked clay/graphite composite that have a much higher percentage of "unknowns" in its composition. Looking forward to your results... 👍

    It is a pity that the end of the magnetic assembly with a levitating graphite rod is in the shadow, which does not allow you to see what magnets it is assembled from. There is also an open question regarding the orientation of their poles.
