Subjects include: fundamentals of electromagnetism and magnetic particles, fundamentals of magnetic testing, magnetic leakage
field measurements, equipment used in magnetic testing, reference standards, demagnetization, metals testing, electric power applications of magnetic particle testing, magnetic testing of metals, infrastructure and aerospace applications, and chemical and petroleum applications.
To focus the magnetic flux at the gate and restrain the decrease of magnetic flux, the magnetic circuit must be insulated from the mold to prevent magnetic leakage
This is due to peripheral magnetic leakage
, whereby, the magnetic field "leaks" beyond its intended area.
The magnets produce a magnetic flux or field in the pipe wall and sensors measure the magnetic leakage
at zones where the pipe wall thickness is not uniform.
The magnets produce a magnetic flux (or field) in the pipe wall, and sensors measure the magnetic leakage
(changes in the magnetic field) at zones where the pipe wall thickness is not uniform.
The new optimized systems will include radiography, ultrasound, magnetic leakage
