What causes magnetism?
Moving electric fields (charges) explains pratically all that we see in our daily lives.
Which elementary particles and how?
If I may hazzard a guess, Krab is pointing out to the spins and angular momentum of quantum particles, which is the origin of magnetism in matter. Spin,for example, isn't "moving charges", and yet, they exert a magnetic moment.
