Discussion Overview

The discussion revolves around the physics of a magnetic toy called the Levtron, specifically focusing on calculating the force between the levitating top and its magnetic base. Participants explore the theoretical and practical aspects of this phenomenon, including the relevant formulas and measurements needed for a project report.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant seeks assistance in determining the appropriate formula to calculate the force between the Levtron's magnetic top and base.
  • Another participant provides a reference to a mathematical description of Levtron phenomena by Professor Michael Berry.
  • Some participants suggest that if the top is stationary above the base, the magnetic force equals the weight of the top, proposing that weighing the top might be a simpler approach than calculating the magnetic force directly.
  • A participant expresses concern about the complexity of expanding a simple concept into a lengthy report and presentation.

Areas of Agreement / Disagreement

Participants generally agree that the force when the top is stationary is equal to its weight, but there is no consensus on the best method to calculate the magnetic force or the approach to the project report.

Contextual Notes

The discussion does not resolve the specific formulas or methods for calculating the magnetic force, and there may be missing assumptions regarding the setup and measurements involved.

hi, I am new to this i hope someone can help
i have a small problem with what formula i should use for my project

i have this magnetic toy that is called the levitron and it levitates this magnetic top over a bass that is also a magnet. I am trying to find the force between the two magnets.


here is the link if you need any more information. http://www.levitron.com/physics.html
 
Physics news on Phys.org
Assuming that the top is just sitting above the base, the force is exactly equal to the weight of the top! And it is probably easier to weigh the top than to find all of the data you would need to calculate the magnetic force.

thats what i thought when i started this project, but to take this simple step and stretch it out into a 6 page report and a 10 min presentation is a little complicated
