🔍 Key Concepts

• magnetic particle inspection principles (how magnetic flux leakage reveals defects) • Difference between circular magnetization (current through part) and longitudinal magnetization (coil around part) • Relationship between orientation of magnetic field lines and the direction of a crack or discontinuity

💭 Think About

• Think about how a surface or near-surface crack becomes visible when using magnetic particles. In which direction must the flux lines cross the crack to create strong leakage? • For the circular method, consider how the current flows and how that affects the shape and direction of the magnetic field inside the part. • Ask yourself: when do you get the strongest, most visible particle buildup – when the field runs along the length of the crack, or when it cuts across it?

✅ Before You Answer

• Be sure you know that with circular magnetization, the magnetic field lines run around (circumferentially) the current path. • Verify which option correctly describes a field that will cut across (not run along) a linear discontinuity. • Eliminate any choice where the field and the discontinuity are described as being in the same direction, because that produces weak or no indications.
