SUMMARY

This discussion focuses on the construction of a magnetic railgun, specifically addressing the calculations for projectile velocity and the interaction between electricity and magnetism. Key equations for calculating projectile speed involve principles of electromagnetism, which dictate that electricity and magnetism are manifestations of the same fundamental force. The conversation highlights the importance of understanding these concepts for successful railgun design.

PREREQUISITES
  • Basic understanding of electromagnetism
  • Familiarity with projectile motion equations
  • Knowledge of magnetic field interactions
  • Experience with electrical circuits and current flow
NEXT STEPS
  • Research the Lorentz force equation for projectile motion
  • Study the principles of electromagnetic induction
  • Explore advanced railgun designs and their efficiency
  • Investigate the role of capacitors in railgun systems
USEFUL FOR

Engineers, physicists, hobbyists interested in electromagnetism, and anyone looking to build or understand magnetic railgun technology.

Hey everyone

I've been wanting to create a magnetic railgun for some time. I have a few questions though.

1. What equations can i use to calculate how fast the "projectile" are moving?
2. Why do the magnets respond like this when electricity flows??

Thanks!

The answer is that electricity and magnetism are the same force, seen from different points of view.
