4. True - or - False
• MPT can detect subsurface cracks 12 mm
below surface
• MPT can be used for Steel alloys with a
chromium content of 10.5 % Cr .
• MPT devices utilizing AC current is used to
detect surface flaws
• In a longitudinal magnetism technique , cracks
parallel to the lines of force will not show

6. + & -
Advantages disadvantages
Can be applied on large surface areas Only applies for ferromagnetic
materials
Can be used to inspect complex parts Magnetic field alignment is essential
Can be applied rapidly Requires relatively smooth surface
Can detect surface and subsurface
flaws
Can’t be applied on painted surfaces
Flaws are produced on the surface Demagnetization is usually necessary
Costs are relatively cheap
