  1. Moving electrical charges create a magnetic field.  Electrons are moving in atoms and molecules.  While not all matter is "magnetic", all matter can be affected by magnetism.  The moving electrons in the copper also create a magnetic field, which is probably more concentrated on the inside of the tube than on the outside of the tube.
