Two items stick out in your note:
To charge a material that can become a permanent magnet it is (in industry) by placing the material in an extreme magnetic field (usually a chamber designed for said purpose). The material is put into a condition (heat, powder, crystallization, or other methods of allowing the magnetic dipoles of the material to be able to align with the presented extreme field. Fields (gauge theory) in physics are serious business, in which great ideas are often planted. Whei it is in this state it is cooled, sintered, condensed, or crystallized to "lock in the orientation of the dipoles.
One way to do this (out of the lab or production floor is to run current through the material. Assuming it conducts)
This high current does/can rearrange the dipoles to less random orientations, improving the magnet some. It is not the primary method of charging a magnet. Only things that are Ferromagnetic, or compounds that form permanent magnets (Samarium/Cobalt, Neodymium, and others) can be magnetized. As pointed out in the attached content there are three categories of materials that show magnetic properties. Bricks do not.
Quote from you: "So if it is coming from the material it must be matter and is matter in motion" A magnetic field is not matter, it is a continuum of force tapering with distance (in most cases with the inverse square law. It is clearly understood to be a field of quantum Electro Dynamics. QED. This force has no mass, is always transparent, can bend and affect other magnetic fields, and Light (which is by the way a magnetic field).

The force can only act as a spring to bounce things, or a motion generator to drag things (electrons) in a conductor. To do so requires it to be powered by something either moving it, or changing its applied force. (see mechanical magnetic chucks) There is no intrinsic energy (fuel to do work) in any magnet, no matter how powerful, or complicated.

I would make one suggestion. Put down Joe's material and get into the real physics from pure scientific thinking and concrete understanding. Then re-read the balderdash in the material from Joe.

I say this as a realist that would wish (with my heart) that there was reality hidden in the material. It is just not there. Faith is dependent on willingness to not know. With warm regards, Jim
