I was crunching the numbers as well and came to that same conclusion. Back to the drawing board it seems...

Thank you again for the advice here are the technical specs of the motor. HP: 1/10 RPM: 2300 Rotation: Reversible Torque (oz-in): 40 Field Volts: 12 Diameter: 3in Shaft Dimension (inches): 5/16 x 2

Thank you for the advice, much appreciated. Would the same apply if I replaced the USB cable with a Parallel port cable?

Hi everyone, What I am wondering is if there is a way to convert 5 volts to 12 volts. The application I will be using this for is a USB driven motor. The USB cable can only handle 5 volts and the motor is 12 volts. So I am wondering if there is a device or something simple to build that can...

Awesome thank you for taking a look at it for me. I think I will stick with your revised equation however. Now its just figuring out the force on one electromagnet.

I have been doing some more research and I've come across this equation from the website http://www.magnetsales.com/Design/FAQs_frames/FAQs_frame.html Here is what it says about the equation, which I have attached to this post as a jpg. What is the governing equation for field strength...

None taken at all. I think that you have a very valid point. I do in a sense have a phobia, I think I just need a way to make it stick and see the end result. But it totally agree with you and thank you for the advice.

I hope so too! ;) I apologize in advance for this and I don't know why I didn't kick myself for this before but, I think I am going about this all wrong. Here are my thoughts. I need to figure out the force of just one magnet. After I have that, then could I plug it into the inverse square law...

Hmm very good advice from both. Thank you for all the advice I appreciate it. It looks like I have some searching to do. Is anyone out there an engineer, and have similar thoughts or experiences like this? Just wondering.

Thank you for the advice! What does the tech program include is it more hands on?

Hey, This might seem like an odd question or whatever but I figure I mine as well ask it. I really enjoy building things, trying new things and being creative. The thing is though I'm not very good at math and critical things like that. I would much rather sit down with a welder and a pile of...

Okay sounds good I will begin plugging in some numbers and playing around with it. Thanks again for the advice it has helped me a ton!

One more thing. Once I have found the force of the magnets could I plug it into this equation as listed in the wikipedia article? The equation is this, or at leas I think. Strength of the magnet divided by the distance from the magnet's center cubed. The answer to that equation would give me how...

Hey Phrak, I have been researching the wikipedia articles you have pointed out and several others. I am using the equation of F={{\mu q_{m1} q_{m2}}\over{4\pi r^2}}. It is show better in the article obviously. What I am having trouble with is finding the magnitudes of the poles. I have found...

Thank you Phrak for the great advice! I will being working on the distance problem using the information you supplied. The strengths and dimensions I listed were from several manufacturers of electromagnets that I am interested in buying. I don't actually have any of the magnets on hand. Could I...
