Magnet repels water. This can be seen by the change in reflection when magnet is moved under bowl with small amount of water in it.

  • The magnet is causing the metal bowl to move which results in the water moving. That magnet is hardly strong enough to make water move.

  • @TheKingPhisher

    Nothing touches the bowl. There is no trick. The experiment is set up so that the very small movement of water is visually detectable.

  • Is the magnet deflecting the water, or the electromagnetic radiation (photons) from the light fixture?

  • @oaney - it is deflecting the water.

  • @oaney - it's deflecting the water.

  • i think you need very strong magnets for this experiment, water only holds that slight diamagnetic property right?

  • Your are absolutely correct. The effect is small even with these powerful Neodymium magnets. Looking at reflection in a very shallow pool of water is a trick to make a very small effect visible to the naked eye.

  • I didn't say it was a trick. I was only suggesting that what is perceived could be due to the movement of the metal bowl if the bowl was magnetic. A magnet doesn't need to touch a metal surface to move it, basic logic and commonsense there for a strong magnetic field coud EASILY move a magnetic metallic bowl if the bowl wasn't clamped down tightly.

    Now as far as moving water, I doubt a regular magnet is powerful enough to move water.

  • @MrAbbusai Yeah, absolutly, but it must be, indeed, a VERY powerful magnet and big aswell.

  • ohh by this can we stop tsunami by using very powerful magnet??

  • @TheBrymanShow even if the bowl was metal the same effect would be visible, the magnet may attract to the bowl though causing a large distortion in th water when the magnets hit stuck onto the bottom
