Magnetism is the force when magnets attract or repel one another. This is the result of electrical charges of tiny atoms. Magnets are useful in holding things together, and can be a gentle force or extremely powerful. Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.

Playing with magnets is one of the first bits of science mostchildrendiscover. That's because magnets are easy to use, safe, andfun. They're also quite surprising.

(push away)? One of the most amazing things aboutmagnets is the way they can attract other magnets (or other magneticmaterials) 'at a distance,' invisibly, through what we call amagnetic field
