Automated Magnetic Field Evaluation for Magnetic Particle Inspection by Impulse

A new method of magnetic field evaluation for magnetic particle inspection is presented. Measurements show that a magnetic field value itself is not a sufficient predictor of detection ability. The evaluation method is based on a magnetic field measurement and the calculation of the impulse of magnetic force on a detection particle. Results are compared with commonly used gauges. Directions of sufficient field indicated by this novel method correspond with directions shown by standard gauges.
