If I drop a magnet through a coil of copper it induces a voltage in the coil. So what happens to the voltage through an copper coil electromagnet if I drop a copper rod through it?
I can't (crudely) create a sensitive enough system to detect a change with copper, but when iron enters an electromagnet it creates a voltage spike on entry and a negative voltage on exit. What theoretically should copper do?
