    The moving magnet creates an electric current in the copper which in turn makes a magnetic field which slows down the fall of the magnet.

    If it wasn’t for this “technology” for lack of a better word, we wouldn’t have some of the great amusement rides we have, like the tower of terror and other rides that drop and also stop, like some roller coasters. It never breaks down and never wears out. I wonder why they haven’t figured out or even tried to find a way to use these in at least trucks or airplanes. Maybe they have and they’re too abrupt or something.

    The magnet will, slowly, lose its flux, or magnetic power.

    In this maybe, but the rides use electricity, not just plain magnets. They will require replacement, but compared to brake shoes, it wouldn’t be anywhere near the same time. Besides, if they didn’t have this system there wouldn’t be a lot of the rides we have.

    The copper bar is sort of overkill; you can get the same effect using ordinary copper plumbing pipe.

    The magnet motion induced magnetic field must always be in such a direction as to oppose the motion of the magnet. Were it not it would be possible to build a perpetual motion machine and thermodynamics prohibits such.

    You were probably wearing your X-ray vision specs that you bought off of the last page in your comic book.
