Does Rolling a Magnetic Core on a Magnet Affect Its Properties?

[Milas]

TL;DR

Do Magnetic properties change

Hi

Quick question related to magnetism

If I have a magnetic core and place that core onto a magnet, then roll the core on a flat surface ( whilst its still on the magnet), does that increase the permeability and magnetic field of that core ? If so, what is the theory behind that.

thank you in advance

Can you upload a sketch please (use the "Attach files" link below the Edit window).

Also, what shape magnetic core? Is it magnetized in some way? And what do you mean by "placing it on a magnet"?

What grade of material is the core made from?
Ferrite, powdered iron, or laminated steel?
Is it toroidal core?
