There are many types of losses in transformers, but some of them are important in such a way that there are many types of losses such as iron, copper, hysteresis, eddy, stray, and dielectric. Hysteresis loss is caused due to molecular friction in a ferromagnetic material, under alternating magnetic field. They flow in closed loops in a plane perpendicular to the magnetic field. The iron loss occurs due to variation of flux density in the transformer core and copper loss occurs due to I 2 R in the transformer winding. Because E is given by , the per unit volume per unit time average of the second term in Eq. The circulation current, called eddy current, cause wastage of electrical energy. Copper loss can simply be denoted as, I L2 R 2 + Stray loss. By tracking the offshore position of the current core and its velocity at 30S in relation to eddies, it is demonstrated that eddy dissipation occurs through a transfer of momentum, where anticyclones consistently induce positive velocity anomalies, and cyclones reduce the velocities and cause offshore meanders. Eddy current losses Eddy current losses are the result of Farady's law, which states that, "Any change in the environment of a coil of wire will cause a voltage to be induced in the coil, regardless of how the magnetic change is produced." Thus, when a motor core is rotated in a magnetic field, a voltage, or EMF, is induced in the coils.
