I am always trying to test something that requires more than one battery and was never able to hold two or three batteries the wires and whatever I was testing at once and still have it work - so never able to test.  No More!

Now i just stick a neodymium magnet in between batteries and one at either end.  The magnets hold the batteries and my alligator clips in place and now I can test what ever I need.

Standard disclaimers apply - this is just something I did.  If you do it and break stuff, hurt yourself or injure others - I am sorry to hear it but that is about it.  These magnets are strong and have a tendancy to snap back together faster than you can stop them.  There is a very good chance that if you are using these with a live circuit that they can very quickly snap into a configuration that can immediatly short circuit and self destruct.

Materials needed:
Batteries 
Magnets - 1 more than you have of batteries
Test leads with at least one end that is magnetic - just like the ones you find with alligator clips on each end.
Something that needs electricity

<p>This is three years late but I just found your suggestion. I had the magnets on hand so I put it together for some temporary Christmas LED projects. It works great and is faster and more reliable than clamps, rubber bands, or tape.</p>
great idea, <br> <br>if need more magnets, you may salvage strong neodymium magnets from defective pc hard drives..
I like it.
Genius!
Very clever!
