Etymology

Origin of hysteresis loss

First recorded in 1890–95

Example Sentences

One major challenge is iron loss, also called magnetic hysteresis loss, which occurs when magnetic fields inside the motor repeatedly reverse direction.

The question has been much debated whether the values of the hysteresis loss obtained by these two different methods are identical for magnetic cycles in which the flux density reaches the same maximum value.

If for transformer or alternating-current magnet building, it should have the smallest possible hysteresis loss at a maximum flux density of 2500 C.G.S. units during the cycle.

If heated to above 135� C., the hysteresis loss soon attains a maximum, but then begins to decrease.

This question is also connected with another one, namely, whether the hysteresis loss per cycle is or is not a function of the speed with which the cycle is traversed.
