Question 2- What is eddy curent? (Physics 2019-20 1Marks AMU +2)

 Answer-

Eddy currents are induced currents in the body of conductor when subjected to changing magnetic flux. They are also known as Foucault current after the name of the scientist Foucault. They are known as eddy currents as they are in the pattern of eddiesin the water.

Que- What is the advantage of eddy current?

The advantages of eddy current testing are: Sensitivity to surface defects. Able to detect defects of 0.5mm in length under favourable conditions. Can detect through several layers.

Que- What is the disadvantages of eddy current?

Disadvantages of Eddy Currents:

There is a major heat loss during cycling eddy currents due to friction in the magnetic circuit, especially where the core is saturated. Thus there is the loss of useful electrical energy in the form of heat. There is magnetic flux leakage.
