1.	With an increase in the density of the material who does it affect the power loss in eddy current?(a) Increases(b) Decreases(c) Does not change(d) Not relatedI have been asked this question in unit test.The query is from Eddy Current Test topic in chapter Non Destructive Techniques of Casting-Forming-Welding II
Answer» Correct answer is (b) Decreases The explanation is: ACCORDING to the power dissipation FORMULA for EDDY currents, power loss experienced is INVERSELY related to the density of the material, that is, with an increase in the density of the material, there is a DECREASE in the power loss.
