Thanks. I was confused, but with your help I understand now.

I think he really meant iron or steel are magnetic (compared to other metals when testing with a magnet) but the poor way he constructed his statement made it confusing and open to misinterpretation.

I thought both iron and steel have magnetic properties…just different retention of magnetism? I guess I'll have to experiment more to see how your statement pans out.

A magnet will tell you of the base metal of the tube is iron or steel.

Differences Between Iron and Steel
Iron substances are magnetized relatively quickly. However, iron types including soft iron lose its magnetism just as fast. These characteristics are particularly useful when strong but temporary magnets are needed such as electromagnets. Steel takes considerably longer to become magnetized, but retains its magnetism for much longer periods. This property, called high retention, enables steel to be used as permanent magnets.

Magnets don't stick to the tube part - definitely to the base.
