A model for magnetic flux leakage signal predictions

Journal of Physics D: Applied Physics, 2003
An analytical model was developed to determine the length of a surface-breaking defect along the direction of the applied field when using the magnetic flux leakage (MFL) non-destructive technique. The theoretical model fits the experimental MFL results from simulated defects.

Leakage Flux of the Trans-Rotary Magnetic Gear

IEEE Transactions on Magnetics, 2019
This paper investigates the leakage flux of the trans-rotary magnetic gear (TROMAG). TROMAG is a magnetic gear that converts a high-force low-speed linear motion to a low-torque high-speed rotation and vice versa. TROMAG is tailored to force-intensive linear motion applications such as backpack energy harvesting and artificial heart in which the gear ...

Importance of Magnetizing Field on Magnetic Flux Leakage Signal of Defects

IEEE Transactions on Magnetics, 2018
The measurement of magnetic flux leakage (MFL) is widely used as a non-destructive technique for inspecting oil and gas pipelines. In this method, many factors can affect the MFL signal, but the magnetization of the pipeline is a fundamental issue that bears consideration.

Horn speaker with reduced magnetic flux leakage

The Journal of the Acoustical Society of America, 1986
By adding a secondary magnetic piece with a partially open magnetic circuit to the front surface of a yoke connected to a primary magnetic piece, the magnetic flux leakage from the main magnetic piece is reduced on one hand and the magnetic flux extending across a magnetic gap is intensified through formation of a favorable magnetic field.

Magnetic Flux Leakage Capabilities and Data Interpretation

CORROSION 1991, 1991
Abstract Magnetic flux leakage principles for ILI is still the method of choice for inspection for both inspection companies and end users. Evaluation of this phenomenon will include an examination of the types of anomalies MFL will detect, its limitations and the data currently available from inspection surveys. Detection

Numerical Simulation and Analysis on Magnetizing Exciter for Magnetic Flux Leakage

Key Engineering Materials, 2011
Magnetic flux leakage (MFL) is a non-destructive testing method used to inspect the pipe and magnetization of the pipe wall to saturation is essential for anomalies to be reliably and accurately detected and characterized. Axial components of magnetic flux density obtained during the MFL inspection have been simulated using three-dimensional finite ...

Leakage-flux suppression in magnetic air breakers

Electrical Engineering, 1958
THE MAGNETIC AIR CIRCUIT BREAKER, during the past two decades, has become a most effective and widely used circuit-interrupting device. The need for increased ratings in magnetic air circuit breakers has required critical studies of and improvements in the various factors involved in the interrupting process in these devices.
