under magnetizing by sine magnetic field with frequency 
is considered. Analysis of main patterns during magnetizing of tested object with surface defect having depth h and width 2b, magnetized by sine field
by means of introduced generalised parameter of defect
It was shown that magnetic field components of defect have complex character and if Bd
4 can be represented by formulas:
Where 
and 
are normal and tangential field components, x, z - coordinates,
For the case, when 2Bd 
0.1
and magnetic field components can be defined by expressions for static field ( = 0). The mentioned expressions were checked on by processing of experiment data published by some authors. Thus, the proposed model makes possible to describe magnetic field of surface flaw during magnetizing by direct and alternative field.
