  1. Force exerted by a magnet

    5 November 2011 - 08:40 AM

    Hey fellas,
    I know its been a freaking long while since i posted or visited here last.
    But i was remembering an old experiment i did back in high school that i couldn't do right. I know that the data i was supposed to see was going to be a positive exponential increase. But my data was too jittery, mostly due to poor experiment setup and execution.

    Ok, this is what i was trying to find:
    If you have 2 permanent magnets ( i used 2 Neodymium barrel type magnets. 1 In Dia, 2 In height) How much force is one magnet being pushed away from the second magnet.

    My hypothesis: As the second magnet gets closer, the first magnet will be pushing away harder. Scaling exponentially, until there is no more space left between the two magnets. As distance between the two magnets decreases the force exerted by the first magnet to move away from the second one increases.


    My experiment design wasn't all that great as i had to basically jerryrig all of the devices together for unintended purposes.
    I used a grooved aluminum yardstick, (grove fit magnets pretty well and easily slid) and there was this electronic force scale that im pretty sure i had to turn on its side and attach to one end of the yard stick. Though, after calibrating, the only real issue was that i used my hand to slowly move the second magnet close. Several attempts were thwarted by jittery hand movements, and some were thwarted by the one magnet being pushed up instead of back.
    I set one magnet on the rail with the backside touching the force scale, while i placed the other magnet on the rail away from the first. i grasped the second magnet and slid it closer to the 1st.
    + = magnet
    - = Rail
    [ = force scale

    [+------------+
    i moved the second magnet closer:

    [+----+
    and so on.

    Also note, i used like sides as to repel one another.


    SO: now on to you guys. IF you would be so kind as to gather the data i was looking for. I don't have any of the equipment necessary, nor the magents either. I would really like it if you would also test several different sizes of magnets too. E.G:
    1cm Diameter, 2cm long: 3cm diameter, 4cm long: 5cm diameter, 5cm long:
    2cm diameter, 4cm long: 4cm diameter, 5cm long: 6cm diameter, 6cm long:
    3cm diameter, 6cm long: 5cm diameter, 6cm long: 7cm diameter, 7cm long:

    Nuclear and particle physics, which are often treated as one topic at lower levels of university, but diverge into individual topics (and into low energy and high energy physics) as you advance.
