    Sideways pull force of a magnet

    The picture should help you get the idea. If I were to hold a magnet x distance away from a magnetic wedge, how do I calculate the sideways force it will generate? Oh I forgot to include, I know the angle of the wedge face to the magnet as well.

    Thanks in advance.

    Trust your own instinct. Your mistakes might as well be your own, instead of someone else's ~BW~ It's kind of fun to do the impossible ~WD~ From now on, I'll connect the dots my own way ~BW~ If I shall be like him, who shall be like me? ~LR~ Had I not created my whole world, I would certainly have died in other people’s ~AN~

    This appears to be the reason all right.

    Just need to push the system a bit more to get the effect from the Muller.
    Good drawing. Thanks. any ideas on making improvements?

      I have some ideas. I just posted them in the Muller thread here.

      If someone can help me calculate this force, I will be making a spreadsheet that will automatically calculate how well this force will cancel cogging on any Muller type system. It will also easily help us design the best angle, etc.

      Hence my urgency to figure out how to calculate this.

      @Everyone,
      ANY ideas? Even if it is just an idea? I know how to calculate the gauss a distance away, and originally thought that is all I needed, but it appears I need more... ANY ideas are welcome, even if you think it may be wrong. Please post!

        the more I think about this. it needs a test just something basic to get some comparison data to see if its worth pushing forward

          Yes I think you are right. Based on this, you could take a completely plastic hot wheel or something, attach a 1" by 1/2" by 1/4" magnet on it at an angle so the front en is closer to the ground and the back end is farther away from the ground. Then just place the car on a sheet of iron.

          If the principle holds, the car will move forward, no? I doubt it works though it seems too easy. Maybe I'm off the wall.

          It happens though when you let yourself think out of the box.

            Well,

            I figured out how to calculate the x plane pull force. Problem is, I only figured it at one point and that took 320 data entry points. If I were to do it for all of the magnets it will take a looong time the way I did it. Perhaps I can gleam some formulas from the data I have now.

            Question.... Does anyone know what formulas they use in this calculator? I am particularly interested how they calculate "Bx"
            K&J Magnetics - Magnetic Field Calculator

            I am learning some interesting things as I do this so even if it doesn't look hopeful I will continue the exercise to see what I can learn.

              Great thread

              Hi there Shadesz ,
              Angled magnetic setups are very hard to calculate because of all the variables especially when theres rotation involved . Ive used angled magnetic forces for a few yeas now and i can say there is some benefits but you really have to think hard in your designs to take advantage of this . The edge of the magnet has the strongest pull but has less surface area than the face , this is what you need to take advantage of if you can . I use iron dust from a drop saw - sprinkled on a peace of paper over what magnetic fields i want to see and in a clear container over the top of pulse motors (slowed down speed though other wize you carn't see chit ) . Ive made a Non linear magnet motor/ generator using this principle - it uses the edge of the magnet for generation and pulses inbetween the magnets for the motor action . Are you going to build something or are you just trying to do some calculations . cheers Jason
