For given applied voltage, what will happen if we increase frequency of the applied voltage?
Correct answer: C. Eddy current loss will remain unchanged
- A. Eddy current loss will decrease
- B. Eddy current loss will increase
- C. Eddy current loss will remain unchanged
- D. None of these
Explanation
Eddy Current Loss is represented as We = (Ie)2 x RcoreWhere,We = Eddy Current LossIe = Eddy CurrentRe = Resistance of coreSo, as per equation it neither depends on applied voltage, nor frequency, then it will remain unchanged.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
