I understand that the magnet strength of the solenoid is increased by the core material's permeability.
I am looking to use an iron core, as I understand that to be highly permeable.
However, for experimenting purposes, I only have access to a local home depot.
They have some plubming tubes which are metal, and also some tubes in the hardware section.
My question is, if I take a magnet to each of those tubes, is it safe to say that the material that has a stronger magnetic attraction to a basic magnet, will be one with higher permeability?
