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.
What is a magnet? A magnet is an object made of certain materials which create a magnetic field. Every magnet has at least one north pole and one south pole. By convention, we say that the magnetic field lines leave the North end of a magnet and enter the South end of a magnet. This is an example of a magnetic dipole (di means two, thus two poles). If you take a bar magnet and break it into two pieces, each piece will again have a North pole and a South pole.
