Eddy currents are currents induced in conductors to oppose the change in flux that generated them. It is caused when a conductor is exposed to a changing magnetic field due to relative motion of the field source and conductor; or due to variations of the field with time. This can cause a...
Eddy Current Testing (ET) Level 3 NDT training course from the world experts in non-destructive testing (NDT) training, examination and consultancy services
What are the advantages of using a bridge rectifier? What are the advantages and disadvantages of connecting batteries in series? In parallel? State one advantage of using an ac over the dc? What is eddy current? Explain. What is the definition of electric current?
Eddy current testing is also widely used in the aerospace industry to detect defects and anomalies in both new manufacturing and in-service inspection roles. Here, Isbell focuses on eddy current technology and its use in the tubing, wire and parts industries.Isbell, Dean A...
Moreover, the magnitude of eddy current can be given when an eddy current “I” is flowing through a core path of resistance “r,” where it can dissipate energy in the form of heat, which can be given in the power equation, power = I2R. This represents the energy that is being ex...

A color sensor is a type of "photoelectric sensor" which emits light from a transmitter, and then detects the light reflected back from the detection object with a receiver. A color sensor can detect the received light intensity for red, blue and green respectively, making it possible to dete...
