Magnets work because of a compressed (closed) combination of syncopated atoms. They are themselves a blockage on the wave of space which we are built upon. Not unlike the earths reliance on the vibrations of the sun which surround it.
A magnet will attract other metals, because a metal has the closest level of confined syncopation to it as compared to biological structures. If a metal does not attract, it can often become attracted by rubbing and pressing a magnet along its surface. This is because the magnets wave is affecting the space around all objects. The “locked” atoms inside of the ferromagnetic material now syncopate, and have a greater extension of group vibration across the space in which it is immediately interacting with, because the group syncopation for the magnet pressed against the semi-compatible syncopations within the ferromagnetic material.
External waves will absorb some of any field, or expand it through additional syncopation.
This is why melting an item down, and rebuilding it within a magnetic field can increase its magnetic properties, as atoms will align to their possible electron specifications within the field. As such, you can create 3rd under 4th locations where fields may vary as the atoms fill back in while excitement settles. Unless the field is an exact match to the atomic compatibility for an element or molecule, not all syncopation will be equal, but they will generate a prime function of fractions within fractions to equalize.
This is also why it is possible to affect biological structures with a sound understanding of these properties. Affecting a face and applying a field while settling the excitements can have profound effects on not just solid objects, but also the body.
