Amorphous Material: A non-crystalline substance created by rapidly freezing liquids of high temperatures.

Eddy Current Loss: When magnetic flux flows, eddy current flows to negate the flux.  This eddy current causes loss is proportional to the resistance.

Hysteresis Loss: By magnetic induction, magnetic domain rotates to have unified direction.  The loss caused by this movement is hysteresis loss.

Load Loss (Copper Loss): The loss that occurs because of the flow of load current when loaded.

No Load Loss (Iron Loss): The constant loss that always occurs regardless of whether loaded or not.
