Magnet Experiment: Investigating Force & Distance

Click For Summary
SUMMARY

The forum discussion focuses on a high school physics experiment investigating the relationship between magnetic force and distance using neodymium magnets. The participant aims to measure the force required to separate the magnets at varying distances, emphasizing the need for practical applications of the model. Key considerations include methods for accurately measuring force and distance, as well as the precision of these measurements. The discussion also touches on the real-world applications of magnetic field strength data, such as in MRI technology.

Hello PF!
I am about to conduct a physics experiment to write my high school level paper on. I initially was going to investigate the Gaussian Gun, but my physics teacher has said that I need to have real life, practical applications of the model, and to also have a variable I can change and talk about.

So, I've decided to change for now, looking more at magnets themselves. We have neodymium magnets and I was winding if calculating the force needed to separate the magnets decrease over distance and maybe plot a relationship.

Do you have any advice?

So explore magnetic force vs. distance? That seems like a reasonable experiment, could be pretty neat.
A few things to consider:
1) How will you measure the force?
2) How will you measure the distance?
3) How accurately will you measure these quantities? (To the nearest mm, cm, etc.)

I've collected data of magnetic field strength vs distance. Could you suggest any ways this information is useful in the real world?
 
How do MRI's work?
