hey, could someone tell me if it is possible to measure the angle of twist of a rigid shaft subjected to a torsional moment at one end by using eddy current testing?
Eddy currents are circular electric currents that are induced in a conductor by a changing magnetic field. These currents are responsible for generating a magnetic field that opposes the change in the original magnetic field, and they can be used for various applications such as measurement of twist angles.
Eddy currents can be used to measure twist angles by creating a magnetic field perpendicular to the surface of the material being tested. As the material is twisted, the eddy currents will be affected and the resulting changes in the magnetic field can be measured to determine the angle of twist.
Eddy currents can be used to measure twist angles in conductive materials such as metals and alloys. Non-conductive materials, such as plastics, cannot be tested using this method.
Eddy currents provide a non-destructive and non-contact method for measuring twist angles in materials. This means that the material being tested will not be damaged during the measurement process and no physical contact is required, making it a safer and more efficient method.
One limitation of using eddy currents for twist angle measurements is that the material being tested must be conductive. Additionally, the accuracy of the measurement can be affected by factors such as material thickness, surface finish, and the presence of other magnetic fields.
