Modern permanent magnets are far removed from the traditional horseshoe magnet. Today, magnets are available in a variety of shapes to suit many applications, and the introduction of magnetic alloys and magnetic-oxide based ceramics has made the simple iron magnets the exception rather than the rule.

Advances in magnet technology over the past 60 years have naturally led to an increase in the number of applications. A modern household contains more than one hundred magnets, ranging from the refrigerator door catch to the motor inductor of the DVD player.

That being essentially an intrinsic property of the material, magnetism is often explained from a model of the atomic structure of the material. In the classic atomic model, electrons (negatively charged) turn at the same moment on themselves (spin) and around the nucleus (positively charged). This movement can be compared to a electric wire which gives birth to a magnetic dipole, in the same way as electricity going through a wire produce a magnetic field.
