TV Researcher needs help w/ electromagnet

[cm.jwmprod]

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.

Hello Chris,

Creating an electromagnet with an iron manhole cover, thick wire, and a car battery is definitely possible. The strength of the electromagnet will depend on the number of turns in the wire, the thickness of the wire, and the strength of the car battery. However, it is difficult to accurately estimate the strength of the electromagnet without knowing the specifics of the materials and setup.

As for powering the electromagnet without tapping into the power grid, you could consider using a generator or a solar panel to power the car battery. This would allow you to create a more powerful electromagnet without relying on the power grid. Additionally, using a stronger and more efficient battery, such as a lithium-ion battery, could also increase the strength of the electromagnet.

It is important to note that creating a powerful electromagnet can be dangerous, and it is crucial to take proper safety precautions. It is recommended to consult with an experienced electrician or scientist before attempting to create a DIY junkyard magnet for TV purposes.

I hope this information helps. Good luck with your project!
