    I have an idea for a lifting force machine.
    Step 1: Get hollowed out cube.
    Step 2: Securely attach magnet to inner bottom of hollowed out cube.
    Step 3: Place a lever on inside bottom of cube behind the magnet that's securely attached to inside bottom of cube so that one side of the lever is pointing towards you and hanging over the magnet.
    Step 4: Attach a vertical bar to the top side of the part of the lever that is not hanging over magnet witch is securely attached to inner bottom of cube. Make sure the bar goes all the way up to the inner top of the cube barley touching it.
    Step 5: Securely attach a magnet to the side of the lever that is hanging over the magnet that is attached to the inner bottom of cube.
    Note: Magnets need to be facing each other with attracting poles N,S or S,N
    Note: The lever is going to have to be really close to the magnet on inner bottom of cube because of how close those magnetic fields need to be to interact. But not so close that magnets can touch.
    The magnet on top connected to lever is pulling the magnet on inner bottom of cube towards it and since the magnet on inner bottom of cube is connected to cube, this pulling force acts as a lifting force. Now at the same time the magnet on inner bottom of cube is pulling the magnet on top downwards BUT the magnet on top is connected to the lever so any downwards pulling force is being converted mechanically by the lever into upwards lifting force. Now if you know anything about magnets you now that there are magnets powerfull enough to lift far more weight then just there own. So essentialy this divice is exploiting the powerfull pulling force of magnets by mechanicaly transforming its magnetic pulling force into mechanical lifting force through the clever utilization of a lever, and walla stuff can be made to fly. Imagine if the magnets in this experiment where electro magnets so the ammount of electrical current going into them determined the ammount of lifting force that it would have. Now imagine this system being used as an attachment that could be placed under or ontop of vehicles to counter the weight of the vehicle and any cargo its carying. Now imagine if this was done with powerfull permanent magnets and turned sideways and placed in an electric generator and had enough strength to pass through the magnetic fields as it propelled itself forwards with its own magnetic pulling force. Signed AMA. If some one can make a You Tube video of this effect in action that would be great thanks.

    So...please help me out here! I'm trying to recreate this as a demonstration for my elementary class, but the science isn't working!! I'm using an 8oz (226g) weight instead of the thousand gram weight, and I've had to be creative as to attaching it to my meter stick (I've used an o-ring/caribiner and string, but all other materials are identical to Jared's. Here's the issue - when I use the lever, my spring scale measures MORE work, not less/easier :/ WHAT AM I DOING WRONG? I won't be able to sleep tonight until I understand this :P

    • @funsciencedemos
      @funsciencedemos  4 роки тому +2

      Stevie......a quick suggestion....1) Are you sure it is an 8 ounce (226 g ) weight?....2) directly weigh the weight with the spring scale and see if it measures 226 g.....3) Spring scales can be very inaccurate unless they are calibrated with a known weight. Let us know the result...we can continue to brainstorm together.
