Abstract: Most inspection companies or any companies that involve in doing this inspection were usually do not have a clear view of which method was best to use in MPI. It is sometimes unclear whether the magnetic field was sufficiently strong to give good indications. So theoretically, both can be used as an inspection tool and company will choose the best method and resolving the inspection. Dry particle inspection was best used when looking for shallow cracks near rough surface. Components with paint or rust on them can reduce the sensitivity of the test yet still allow for the desired result. Wet suspension Particles are when particles are applied while they are held within a liquid carrier, allowing for even coverage, and to highlight leakage. It provides optimum contrast with the tested surface, allowing for greater detail than dry particles. They are particularly useful for smooth surfaces as these particles will settle in rough surfaces. The objective was to perform Magnetic testing analysis on selected bolt using dry method. To perform magnetic testing analysis on selected bolt using wet method. To determine the sensitivity comparison between wet and dry method on selected bolts. To conclude wet method magnetic testing has been proven to be more sensitive to defect compare to dry method magnetic testing as evidence by Table 3 at 70% and 50% respectively.
