Magnetic Field Generation In the early nineteenth century, Hans Christian Oersted made a pivotal observation: an electric current coursing through a wire could alter the orientation of a nearby compass needle. This observation implied that the wire’s electric... by Raman Singla | Sep 2, 2023 | Magnetization Methods
Magnetization Methods Several techniques are available to create a magnetic field within a component to facilitate evaluation through magnetic particle inspection. These methods are often categorized into two main groups: direct and indirect magnetizing methods.... by Raman Singla | Sep 1, 2023 | Magnetic Field Orientation
Magnetic Field Orientation and Flaw Detectability To effectively examine a component for cracks or defects, it’s crucial to recognize that the alignment between the magnetic lines of force and the flaw holds great significance. Two primary categories of magnetic... by Raman Singla | Aug 31, 2023 | Particle Inspection, Uncategorized
Types of Currents for Magnetic Particle Inspection AC (Alternating Current) Alternating current oscillates in direction at a frequency of 50 or 60 cycles per second. In India, a frequency of 50 cycles is standard. As AC is commonly available, it is a convenient choice...
