Direct  current  flow  method  may  be  used  when  detecting  discontinuities  at  or  near  the  outer  surface  of  the  part. The  magnetizing  current  should  be  applied  for  a  duration  of  .5  to  2  seconds  with  a  minimum  of  two  shots. In  order  to  indicate  the   presence  of  all  discontinuities , at  least  two  separate  examinations  shall  be  performed  on  each  area. During  the  second  examination, the  flux  lines  shall  be  directed  approximately  perpendicular  to  those  used  during  the  first  examination. A  different  technique  for  magnetization  may  be ...

Components   in   which   length   predominates,   can   be   readily   magnetized   in   the   longitudinal   direction   by   an   encircling   coil. For   this   technique,   the   magnetic   field   is   produced   in   the   part   by   wrapping   cable   around   it   or   placing   it   within   a   multi   turn   fixed   coil. Passing   current   through   a   coil   encircling   a   section   of   the   test   part  or   encircling   the   part   produces   a   magnetic   field   parallel   to   the   axis   of   the   coil.   Strongest   indications   are   produced   when   the   length   of   the  ...
