Magnetism is a class of physical phenomenon that includes forces exerted by magnets on another magnets. It has its origin in electric currents and the fundamental magnetic moments of elementary particles. These give rise to a magnetic field that acts on other currents and moments. The magnetic state of a material also depends on temperature of the surroundings.

 Answer is electrons. The "spin" of particular electrons around particular atoms (Fe, Ni, Co, Gd) can become "aligned" which produces a magnetic field.
