Explanation:

Magnetism is related to electric currents. Ampère's law and the concept of moving charges (which form electric currents) creating magnetic fields are fundamental in physics. Magnetic monopoles are still theoretical and not confirmed to exist in excess. Radioactive decay is about nuclear processes (emitting particles like alpha, beta, gamma). Neutrinos are weakly - interacting particles and not the cause of magnetism.

Answer:

electric currents
