  1. pole strengh is a measure of the force exerted by one face of magnet on a face of another magnet and represented by equal and opposite poles.                                                                                                                                              pole stength = magnetic moment/ magnetic strength                                                                                                               it is derived by use of concept of dimensions                                                                                                                  = A.L.L/L = A.L = AM                                                                                                                                              WHERE a is current, lenght is in metres also magneic moment = cureent * area where l square or l.l represent area
