SUMMARY

The discussion focuses on calculating the attractive force between an electromagnet and a permanent magnet. A key resource mentioned is the Wikipedia page on "Force between magnets," which provides foundational equations for this calculation. Participants emphasize the importance of modeling one magnet as the other when determining the force between two electromagnets or two permanent magnets. The conversation highlights the complexity of magnetic fields while seeking a simplified functional equation for practical applications.

PREREQUISITES
  • Understanding of magnetic fields and forces
  • Familiarity with electromagnetism principles
  • Basic knowledge of mathematical modeling
  • Access to resources like Wikipedia for foundational equations
NEXT STEPS
  • Research the specific equations for calculating the force between magnets using the formula from the Wikipedia page
  • Explore the differences in force calculations between permanent magnets and electromagnets
  • Study the effects of distance on magnetic force and how to model these interactions
  • Investigate simulation tools for visualizing magnetic field interactions
USEFUL FOR

Physicists, engineers, hobbyists working with magnets, and anyone interested in understanding the principles of magnetism and electromagnetism.

I am aware of the complexity of magnetic fields, all i need is a ballpark functional equation of distance between an electromagnet and a permanent magnet. Can anyone point me in the right direction?

Thread 'Colors in a plasma globe'

I have a common plasma globe with blue streamers and orange pads at both ends. The orange light is emitted by neon and the blue light is presumably emitted by argon and xenon. Why are the streamers blue while the pads at both ends are orange? A plasma globe's electric field is strong near the central electrode, decreasing with distance, so I would not expect the orange color at both ends.
