What is copper oxide on pennies?

When oxygen binds with copper, they form a new molecule known as copper oxide. Copper oxide is brownish or sometimes black in color (depending on other things in the penny’s environment). This is why most pennies you see look dirty or tarnished—it’s not actually dirt but copper oxide that makes them look so dull.

Can you make copper magnetic?

This is simply impossible, neither with copper nor even with superconducting magnets (superconductors are diamagnetic substances, but they do not repel ferromagnetic iron, under any circumstances). To repel iron you need the time-varying magnetic field – not the one produced by permanent magnets.

How to tin a copper soldering iron?

When you tin a tip, you cover it with a thin layer of solder. Tinning stops your tips from oxidizing by creating a protective layer between the air and the iron. It’s essential to keep your tip tinned, since iron oxidizes rapidly. Oxidation prevents the tip from transferring heat efficiently.
