The battery is shorted by the coil between it's ends which makes a magnetic field through the coil. It's a very low resistance so the current is high and a strong magnetic field. But I can't picture how this is creating a force on the battery since the magnetic lines are parallel to the battery. I can only imagine the current is limited by the battery internal resistance, so not much of a comparison for life span. But that says to me the wire can be something cheaper with higher resistance and not impact the motive force. I wonder if there is a child's toy product in here some where. It most likely eats batteries like kids eat jelly beans. -- Rick C. - Get 1,000 miles of free Supercharging - Tesla referral code - https://ts.la/richard11209

I was thinking this was about making contact and forgot they are magnets. Cool, thanks. I might have to make one of these. I'll need to get bare wire. My buss wire is enameled. A friend with kids would love it. The kids might like it too. The coils will stand up better if they are wound on plastic tubes, but the movement of the coils is pretty cool. -- Rick C. + Get 1,000 miles of free Supercharging + Tesla referral code - https://ts.la/richard11209
