Likewise, I didn't until today realize that almost all materials react in some way to magnetic fields. This was completely new to me.
Most materials react with a minuscule repelling force to magnetic fields. These are the so called Diamagnetic materials. Then there are the Paramagnetic materials that react with a minuscule attracting force. Finally, we have the Ferromagnetic materials such as iron that react with a relatively strong attracting force, and a permanent magnetic filed can be induced.
All of this is relatively easy to explain with the Velcro model where photons communicate magnetism between materials.
A material hit by polarized (magnetic) photons is unlikely to react in a completely neutral way. Some reaction is to be expected. The photons are likely to be reflected, at least to some extent.
The stronger the reflection, the stronger is the magnetic interaction. The reflection is in turn of two types. The Photons either bounce directly back, or they flip and bounce back facing the other way. If they bounce back without flipping, we get an attracting magnetic effect. If they flip, the effect will be a repelling force.

In most cases, the effect is weak, meaning that there is a lot of scatter and little reflection. However, some materials reflect rather well, and the best reflectors, the so called Ferromagnetic materials, reflect without flipping the photons.
Why exactly some materials reflect better than others, is not immediately clear. However, the Velcro Theory does in fact predict some kind of interaction, simply because some degree of reflection is what we would expect.
