Magnet Experiment: Investigating Force & Distance

Click For Summary

Discussion Overview

The discussion revolves around a physics experiment investigating the relationship between magnetic force and distance, specifically using neodymium magnets. Participants explore practical applications of the model and considerations for conducting the experiment.

Discussion Character

  • Exploratory, Homework-related

Main Points Raised

  • One participant suggests measuring the force needed to separate the magnets as a function of distance and plotting the relationship.
  • Another participant raises questions about the methodology, specifically how to measure force and distance, and the accuracy of these measurements.
  • A different participant mentions having collected data on magnetic field strength versus distance and asks for suggestions on its real-world applications.
  • A later post introduces a question about the workings of MRI machines, which may relate to the broader topic of magnetism.

Areas of Agreement / Disagreement

Participants generally agree that exploring the relationship between magnetic force and distance is a reasonable experiment. However, there are multiple questions and considerations raised regarding methodology and applications, indicating that the discussion remains unresolved.

Contextual Notes

Participants have not yet established specific methods for measurement or the accuracy of those measurements, leaving some assumptions unaddressed.

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?
