Need help thinking of something conductive and magnetic?

I am trying to attach some led lights under a shelf and also need to make them removeable, i need to find something that is conductive as well as magnetic. My original idea was to just get some small nickel or ? plated screws and just wrap wire around them and screw them in but not completely sure of that idea working. I already made the lights and have small neodymium magnets that im going to attach to them but just need some ideas of what to use for under the shelf....thanks


Ive thought of clay, or glue and other stuff but idk.
im putting 4 lights up.
and there will be a switch to shut off power to the material when not in use so there's no safety issues.

This may be what everyone else is getting at but the contacts don't actually have to be the magnets. Just attach magnets both sides, or one side with a magnetic plate on the other, and have separate contacts that handle the power transmission. If the contacts have a slight spring in them they will always contact when the magnets are holding on.

You can buy iron sheet or iron thin flat strips.
Plumbing pipe support perforated strip will do it ( see pic ) under $2..

If you are into savings money,  take apart some food cans still
made of tin plated iron and cut them into strips.

How are you attaching the series resistor for each LED ?

These are my lights!!

I like the tin can idea, that way i can make designs out of them.
Is stainless steel conductive? i know its not magnetic.

Depends on the kind of stainless, some are less magnetic then others.

Good you know LEDs need a resistor in series.

Yea i have access to a toyota hybrid inverter part and it has 3 big stainless plates on it, they are not magnetic but im sure they are conductive, not sure if they are just used for heatsinks though. Going to test them out.

These are the lights. once this is finished i will have an instructable written up.

Yes its conductive and yes it magnetic.

BTW you need to assign best answer on your last question .........................

Done ;-)
Go to your local home center and pick up a cheap piece of galvanized steel and a pair of tin snips. Vut strips of the steel to the size you need and use double sided tape or screws to secure it where you need it. Then you can solder the wires from the power source and switch to the strips.

Galvanized steel? Like fence posts?? Doesn't it have a coating on it that would inhibit conductivity?
The coating is Zinc which is a good conductor.

A pair of "brass" drawing pins will work - They are actually plated steel and magnetic.

Probably get these at michaels? I will have to try these...

Salvage the spring and pad from a battery clip. I'm sure you can find both magnets and something battery operated at the dollar store.

Look around for a piece of copper or brass plated steel. Even plated tubing will work if you split it open and hammer it out flat.

Sounds expensive!!! Don't they make copper foil like aluminum foil, i would need to make a good connection to it though... never "brazed" before..if thats the correct word..
