Explain eddy current loss.
What will be an ideal response?
Alternating current in a conductor or circuit sets up an alternating magnetic field. Eddy currents are induced by this field in any metal near the conductor. For example, eddy current losses occur in the iron cores of reactors, transformers, and stator windings in ac generators and motors. A reduction in eddy currents is achieved by laminating the cores used in ac equipment. However, there are small I2R losses in each lamination of the core.

Freeport McMoRan engineers estimated that the capital investment necessary for recovering valuable metals (nickel, silver, gold, etc.) from a copper refinery’s wastewater would be $150 million. The equipment is expected to have a useful life of 10 years with no salvage value. The amount of metal currently discharged in the wastewater is 12,500 pounds per year. The recovered metals are expected to have a selling price of $250 per pound. The efficiency relation of the recovery operation is represented by X 0.5, where X represents the efficiency in percentage. What value of X is necessary for the company to break even? Assume i = 10% per year.
