Restricted Parking Zone Program (RPZ) How to Initiate an RPZ Program for your Neighborhood. In order to establish an RPZ, there must be a significant degree of parking by non-residents. The Seattle Municipal Code (updated in June 2009) specifies the threshold that must be met in order to establish an RPZ.
A magnet (from Greek Î¼Î±Î³Î½Î®ÏÎ¹Ï Î»Î¯Î¸Î¿Ï magná¸tis lÃ­thos, Magnesian stone) is a material or object that produces a magnetic field.
A magnet is an object or a device that gives off an external magnetic field. Basically, it applies a force over a distance on other magnets, electrical currents, beams of charge, circuits, or magnetic materials. Magnetism can even be caused by electrical currents. While you might think of metal magnets such as the ones you use in class, there are many different types of magnetic materials. Iron (Fe) is an easy material to use. Other elements such as neodymium (Nd) and samarium (Sm) are also used in magnets.
