I have to build an electromagnet for project.. the only restrictions on it is that it must pick up a lot of quarters.. and it uses a supplied 12V DC power source.
I was wondering how would I go to do this?
I'm thinking about using just the regular coiled wire method.. with a few other things, and I want some opinions + ideas of some DIY experts over here
It it scored by two methods.. picking up the most amount of quarters for a bonus..
And the ratio of the mass of the quarters picked up over the mass of the electromagnet itself.
I was thinking of using some extremely light batteries.. (lith ion perhaps?) to bump the power up and get power through the wires; I can safely do this by just putting the DC voltage in series with the batteries, correct?
Also.. what kind of batteries are the lightest, and where would I go to obtain some?
And I was just wondering about things like.. wire composition, weight of the wire, and just wondered if any of you great head-fi DIY enthusiasts would have any idea concerning these matters.
Any other ideas that I haven't thought of.. or words of caution, would also be greatly appreciated.
Thanks in advance,
K
