SUMMARY

Chris, a TV researcher, inquired about creating a powerful electromagnet using an iron manhole cover and thick wire powered by car batteries. The discussion highlighted that while DIY electromagnets can be constructed, achieving significant power without grid access is challenging. Suggestions included experimenting with wire gauge and battery configurations, but the feasibility of making a strong enough magnet for visual effects remains uncertain.

PREREQUISITES
  • Understanding of electromagnetism principles
  • Familiarity with wire gauge and resistance calculations
  • Knowledge of battery specifications and configurations
  • Basic skills in DIY electronics and safety precautions
NEXT STEPS
  • Research "Electromagnet design principles" for effective configurations
  • Explore "Wire gauge impact on electromagnet strength" for optimal wire selection
  • Investigate "Battery series and parallel configurations" for increased power
  • Learn about "Safety measures in DIY electromagnet projects" to ensure safe experimentation
USEFUL FOR

TV production researchers, DIY electronics enthusiasts, and anyone interested in creating electromagnets for visual effects or experimental purposes.

Hi-

I'm a researcher for a TV production company, and I'm trying hammer out a basic idea - perhaps members of this forum could enlighten me a bit, as my science knowledge is a bit weak...

How powerful of an electromagnet could I create with an iron manhole cover, wrapped with rather thick wire and a (or a few) car battery(ies)?

Is there a next step up in powering a magnet like this without tapping into the power grid?

This being TV and all, the classic D battery & nail setup won't work. I have visions of a making a DIY junkyard magnet, making things like monkey wrenchs leap. I could very easily be misunderstanding this concept, though...

Thanks,
Chris

Of course, you ought to just try it. That's the best way. But, frankly, it is unlikely to do what you want.
