Thanks a lot everyone for your insight. This helps a lot! What about silver plating? or Silver Nitrate? With the silver nitrate growing crystals on copper wire experiment could this be achieved with a small plating of silver on a penny in the same way or would it require diff chemicals?

Just like the experiment in high school using zinc powder and sodium hydroxide, is there a way to use real gold plating without having to melt real gold. Such as gold nitrate? Is gold nitrate rare, expensive or dangerous? Thanks!

Thanks! This helped a lot!

I am wanting to use a neodynium magnet to make a traffic light change when i pass over the trigger in the road with my motorcycle but I figured if the magnet is too strong it has to be doing something to the motor or electrical circutry on the motorcycle. So I thought that I would try to shield...

Is there a material that blocks or reflects magnetic fields such as a field from a neodymium magnet?
