| # | Lesson | Type |
|---|---|---|
| 01 | Magnetism Introduction to magnetism, magnetic poles, and the basic behaviour of magnetic materials — the foundation for understanding MPI. | Lesson |
| 02 | Properties of Magnet Key properties of magnets: attraction, repulsion, polarity and behaviour in the presence of ferromagnetic materials. | Lesson |
| 03 | Magnetograph and Properties of Lines of Force Visualising magnetic fields with magnetographs and learning the rules that govern lines of magnetic flux. | Lesson |
| 04 | Types of Magnets: Horseshoe Magnet A closer look at the horseshoe magnet — its geometry, field lines and practical role in inspection. | + Knowledge check |
| 05 | Classification of Magnets How magnets are classified — natural vs artificial, permanent vs temporary, and their relevance to MPI. | Lesson |
| 06 | MPI in Brief A concise overview of Magnetic Particle Inspection: what it detects, how it works, and where it is used. | Lesson |
| 07 | MPI Limitations and Direction of Detection Understanding what MPI cannot detect, and why the direction of the magnetic field relative to the discontinuity matters. | + Knowledge check |
| 08 | Fleming's Right Hand Rule Applying Fleming's Right Hand Rule to determine the direction of induced magnetic fields in current-carrying conductors. | Lesson |
| 09 | Electromagnetic and Lighting Waves Introduction to electromagnetic waves, their spectrum and the role of light in NDT visual inspection. | Lesson |
| 10 | Hysteresis Waves Magnetic hysteresis, the B–H curve, and how materials respond to changing magnetic fields. | Lesson |
| 11 | Uses of Hysteresis and Soft vs Hard Magnet Practical uses of hysteresis and the difference between soft and hard magnetic materials in inspection. | Lesson |
| 12 | Types of Current AC, DC, half-wave and full-wave rectified currents — and how each affects MPI sensitivity and field penetration. | Lesson |
| 13 | MPI Methods and Techniques Survey of MPI methods and techniques: dry vs wet, continuous vs residual, and yoke, prod and coil techniques. | + Knowledge check |
